Sourcing hopper style window catches

[Boink]

New to the forum and hope this plea for help is in the right area. In short I'm trying to help my brother in law sort a few things on his recently acquired, unfinished boat. Struggling to find window catches to match the ones pictured. Think they're aluminium, 1.5 to 2 mm wide with a raised box style section on the back of the catch which adds a bit of strength. The boat is circa 1990, and I've seen a few boats with these catches so hoping they're not discontinued. Need ten in total to enable him to take tape off his windows. 

Thanks in advance for any help/manufacturer leads anyone can give.

Circa 1990 this type of catch was  used by the window makers Severn Yacht Services or Supplies of Worcester.  They have reincarnated a few times since then, but should be traceable if they are still about.

 

However the catches are only a piece of box section aluminium alloy.  A search of the model engineering suppliers websites  should find a suitable length to cut your new ones out of.  

 

That said, what is wrong with the existing ones?  The plastic washers next to the glass have a tendency to disintegrate, but that does not stop the catches working.  The pivot was riveted to the box section and they will be a bugger to remove without breaking the glass.

Thanks so much for this, Inc the box section tip and removal advice. I was wondering why no rubber washers outside. The problem with the existing ones...is there are not enough of them. The chap he bought it from was selling as a completed project, but having admired the new flooring, shower, kitchen etc on viewing, he (and I tbf)  missed the fact that 5 windows had no catches.

I suspect some are not there. Belfast has similar catches; some are missing altogether and some have been replaced by pieces of wood of similar shape, bolted to the window. I have it in mind to make new aluminium ones from box section as you have suggested (but possibly bolted rather than rivetted).

I've had no joy to date finding something similar, but a good neighbours just cut and drilled some aluminium strip - slightly thicker than original - for me. Going to try gluing something to hold onto the surface in place of the profile of original. Thinking a small section of square profile hardwood strip painted metallic. Sticks like #### should do it.

Precisely, and that is what I used to make replacement catches on the Severn Yacht windows on Helvetia. From recollection I bought the box section from B&Q. I drilled the original rivets out, filed a section of box section off the ends to create flat sections, and and replaced the original rivets with pop rivets of suitable length, using a thick piece of leather between the glass and one of the flat sections.
