RE what were they thinking...they weren't really and they were not as good as they thought they were. I should have gone to Brinklow from the off, hay ho, live and learn.
The fuel cap was a large threaded, at both ends, BSP pipe cut in half and welded up. I got it from Thomas Graham in Kendal.
I do have the original gear stuff but not the original wheel which I had cast in bronze not cast iron.
If I had an original iron one I would have it fitted but any chance to bling it up I take.
Engine is a Lister JP2M with a 2:1 Lister Blackstone 3G(?)
