Thanks for the thoughts.

It could well be a self-tapper, StationX, as it goes into the alloy casting. However, I'd have to have the head re-formed as it's not normal. It's most like a watch screw, but I've not found any with that coarse a pitch. I have an account with Cousins as I do some light watch repairing, but their screw selection is poor and lacking detail in the catalogue or online. HS Walsh could be a better idea as they seem to have more information about threads and head dimensions. Perhaps a self tapper and an evening with loupe and file...

emeritus - I knew someone would have a very specific book! It's amazing how little centralised information there is easily available online about the sort of minutiae one would have thought enthusiasts would be eager to post, based on single interest websites.

David - it's a 1942 Contax, so not far off. Microscopes sound a similar area (why I thought of looking at watchmaking standards) so I'll see what I can find online about that.
