Just got a Xenar in a Compund V without the front plate (you all probably saw it on eBay).

I want to make the front plate out of aluminum and probably try to use the speed dial out of a Compound IV. The piston looks the same size in both IV and V.

I would however, need an aperture scale. I can try and do that too but I would need a guide. Would anyone here be willing to trace, draw, photograph (or whatever option you think is best) their scale and email it to me so I can make one?

Maybe you know of a source in the Internet with a drawing or schematic to download?

Your help would be greatly appreciated.
PS: I will also be looking for a flange (90mm) in no time.

Thanks!
