Can anyone confirm the thread size of the rear trigger guard screw for a Superstar / Meteor and other models? I am carrying out a little cosmetic work on a Superstar and the screw is a bit 'challenged cosmetically' although does work. I have tried various screws from my collection but failed to find a replacement. Searching around on this forum and the internet in general leads me to the conclusion it could well be UNF 8-36.
I know I could buy a new one but that irks me a bit although to be fair, a search for unf 8-36 screws shows they are not very cheap anyway.

I am told you can re-tap to 2BA but I see no need to do that. It might be more fun to get a 8-36 die and cut a new thread on a slightly oversize screw.

Interestingly the front stock screws can be replaced with 4mm although I doubt that is the original size.

All help appreciated.
Cheers, Phil
