  1. Nope. A Model Bakery was established in 1926 in Widegate Street, just off Bishopsgate, but that's nowhere near an adjacent waterway.
  2. Thanks Mike (Pluto). That clears that up! Some sort of covering on the boiler, and most definitely a water sight gauge.
  3. In all the other examples of such steam cranes in that set of images, the chimney is shown dead centre of the boiler. So it would appear that the chimney is sat dead center of the near cylindrical 'building' as it appears to be. The catch is, the exposure of the boiler would be much the same as the chimney - dark. But it isn't. It's quite light, and the shadow of the circular chimney clearly makes it round, so too does the shadow of the circular 'building', and it looks to be farther away. I'm not completely conviced my estimation is correct, nor am I convinced the 'lighter' boiler with chimney central is correct. We need the stationary engine move out of the way to be able to tell for sure.
  4. Indeed, though a tad more complicated, and represented by the term Nominal Horse Power (NHP). The same delineation was used with self propelled traction engines. From 'A Century of Traction Engines' by W. J. Hughes, member of the Newcomen Society; of the Road Locomotive Society, and of the National Traction Engine Club; "The term nominal horse power (n.h.p.) is really a hang over from early days, probably deriving from the 'horse power' machines or horse works devised to use horses for driving threshing machines and other barn machinery. One type of horse works was a kind of treadmill, where one, two, or three horses side by side, walked on inclined endless belts which moved beneath them, the power thus generated being taken off through a shaft, gearing and universal joints. Another kind was a sort of windlass, the horses being harnessed to the arms, and walking around in a circle. This type was in use until the 1890's or later: a 'one-horse' machine was awarded a silver medal at the 'Royal' at Carlisle as late as 1880. Thus the manufacturer of a 4 h.p. portable engine would intend to purvey to non-technically minded farmers that his engine developed the same power as a 'horse-power' in which four horses were used. In actual practice, the term was quite wrongly used, one nominal horse power being deemed to be equal to '10 circular inches of piston area'. To work out what this meant, or what was supposed to mean, take the square of the cylinder bore and divide by ten to obtain the n.h.p. Example: a cylinder of 9-inch bore: 9 x 9 = 81 : 8 n.h.p. engine! Or cylinder of 6¼-inch bore: 6¼ x 6¼ = 40 nearly : 4 n.h.p. " None of this took into consideration boiler pressure or even stroke, but gave a rough and ready measurement. My youngest daughter applying one actual horse power (George) at Blists Hill.
  5. As I see it, the stationary engine has a tarp over it with the last part of a word showing which could be '. . . . . WORT*Ltd'. [CLAYTON & SHUTTLEWORTH?] Lying along the top of the boiler would be the chimney in a horizontal position, showing as a long horizontal ridge, covered by the tarp. The smaller wheels will be at the front of the engine - the smokebox end. And water level gauge would be at the firebox end where the driving controls would be. What might appear to be 'windows' of the distant structure, may well be hooks on the cross piece of the drawbar, to which chains would be attached connecting to a harness and collar (as in horse). The chimney with rain cap belongs to the crane just beyond the stationary engine, which can be seen as a bulk beyond the front wheels of the stationary engine, the jib also. Nothing to do with the distant structure. I don't know what the building is in the distance, but it does resemble a windmill without sails. The shadow suggests it is circular, and appears to be made of stone. No idea as to where it may be, other than some broad waterway under construction. Bet that kettle would be a three gallon at least.
  6. It could be a windmill without sails. It appears to be circular with a tapering rise to it.
  7. Yes, there was a thread on that a short while back. Forgotten the lock name.
  8. Ths scolloped side walls are reminiscent of some on the Canal du Midi.
  9. A little more on this location: https://baldexplorer.com/saving-our-waterways/
  10. I spy the sidecar wheel of a motorcycle and sidecar under the tarp . . .
  11. I do not know the person, but the surname looks like Franz. The individual letters match others in the note, save the 'z', for which there is no comparison - except it's not a 'y'.
  12. In the case of SPRY, I disagree. What "use" would that be? Certainly not carrying. Where she is now, she is in prime condition in a dedicated enclosed building with access to the public to view both inside and the entire hull shape from ground level, the latter which will never be seen if in the water. Plus there is the issue of being open to the elements afloat, and all the required extra maintenance that goes with keeping a wooden craft afloat - who pays for that? It's one of a kind, where it is now is possibly the best place for it. The romantic dreams of seeing them sailing? It goes with the possible cost of losing such craft forever simply due to maintenance costs and possible neglect - with the possibility it may end up on the bank again, seeking funds to restore and build a permanent covered housing. At Blists Hill, SPRY is one of a whole range of exhibits that can be enjoyed by the general public from a traditional Fish & Chip shop, candlemakers, horse bus, chemist, ironworks and more. Afloat, it may seem just another old barge in need of perpetual ritual docking - away from the public eye.
  13. MP describes them well. But I have never considered a 'pound' to be the water between a set of gates at either end of a lock. Whilst when a set of gates are open, the water within the lock is 'part' of a pound, but when closed at both ends it is just a lockful of water taken from the upper pound to raise/lower craft. A Stop lock has gates both ends, and the rise is usually small. But a Stop lock cannot be just a single gate across a waterway, as you would need to lower the entire pound to pass through, wasting much water in the process. However, where single gates are installed, it is usually either side of an aqueduct, and in one case I have seen - a tunnel, which are correctly called Stop Gates, designed to be closed, or automatically closed by water flow, in the event of a breach.
  14. Welcome David. As Aspley (the one I know quite well) is in Beds., I think you mean Apsley! Slip of the finger. SNOWDROP in action, swiftly followed by SICKLE. towing an 'opper. Late eighties, Berko.
  15. Beverley! Where did I get Beryl from? Well, it starts with a B. (Poor excuse). Don't remember the Morris Minors, but I only appeared on the scene in '79.
  16. Roger Alsop is correct. There's a lot more on PEARL (both of them, the ex Steamer formerly BARON & the TCO boat) in this older thread: Also mention of POYLE, the wooden boat that was Beryl's home at the time (early eighties), and which was the 'Welcoming' boat in Aylesbury basin.
  17. Bug remover (from vehicle bodywork) would remove the residue but beware of what additives are within, though any cooking oil left to soak into the label will also do the job, even the natural oils from fingers will do it, but patience will be needed. Blimey David - that's a bit perfect! I'd be frightened to go near that one.
  18. "A risky hobby"? It's a design to fit a purpose. Without my old Petter manual to hand (so working from memory and a little experience of wet and dry sump engines) you will find the PD2 a wet sump engine - there is no separate oil tank. In most wet sump engines, the crank rotates above the level of sump oil. Also, a crank thrashing around in oil is not the primary source of lubrication for main and big end bearings. 'Splash' lubrication was a common factor in more primitive engines before forced lubrication, early motorcycle engines spring to mind, and even the later Panther big single relied on splash lubrication for a long time. With the Petter, the oil pump forces oil through the oil cooler to bearings and the valve gear, mostly through external pipes which help to aid cooling from the forced air draught. Water jacketed engines do not run so hot, so many oilways are drillings through blocks, and piston to bore clearances are generally smaller than air cooled, the latter wider to allow for piston expansion under load. Edited to add: Some say that allowing the PD to run at slow speeds on tickover will exacerbate stress and fatigue on a crank, and that this may contribute to failure. Diesel engines do not like running slowly, even though the owners like it for the sound.
  19. We had a PD2 that came out of a ships lifeboat. After installing it in YARMOUTH, we spent many years slogging around the system from Guildford to Gargrave, taking in the Thames and Trent. Never missed a beat. Straight through pipe - you could hear us coming. Get in a tunnel and the rythyms echoing from the tunnel roof from the exhaust would have you dancing on the back step. We'd heard about their cranks breaking, and one or two knowledgeable folk (ex-boatmen) had theories, including making them slog at low rpm, to poor starting techniques. Another suggested leaking oil coolers causing pressure drop. I always turned mine over a dozen times or so with the lifters up, hit the starter, drop the levers and she'd fire instantly, never failed. But one could not start her by hand, took two on the handle. Roger and I did it once. And I lost count of the times I'd forgotten to take the gas bottle cap off the exhaust to be followed by a clank on the roof as it landed, never accompanied by a splash oddly enough. Sold the boat in late '92, and within three months heard the crank had broke. The chap also had caused damage to the Z bar, doing something that forced the bar and tiller so far forward, he had to cut some wood off the tiller handle to clear the top of the hatches. I had heard that BW were offered a bunch of PD's from stationary sets to replace aging RN's, but don't know the truth in that. Maybe they were engines destined for landing craft and no longer required. 'Chip fryers', they weren't quiet mechanically being air cooled and much tinware. The three pot version in TYCHO. Sods to work on. PS: NOTE - the flywheel at the gearbox end. A PDV8 generator set (image courtesy of young Mr. Riches.) Bet that sounded good!
  20. SPRY looks rather magnificent now, with staging alongside to view the interior. Blists Hill Village. https://www.nationalhistoricships.org.uk/register/606/spry
  21. I tend to agree. The number looks to be 780?4, a 2-6-0 introduced in 1953, designed at Derby. Weight loco 49t 5cwt. 65 built in that class. Could be 78064, in which case it was the last in that series. Four are preserved: https://preservedbritishsteamlocomotives.com/2mt-78000-78064-2-6-0-br-standard-class-2/
  22. What a fabulous film. Such a wide ranging view of life as it was, and as it changes. Great character. R.I.P. Alan Holden.
  23. True. My piece was exposed to the elements. Big difference!
  24. Had it been ply, it would have disintegrate long ago. This was painted on plywood in the 1980's, and photographed here 20yrs later.
  25. The flag does sort of give it away.
