Webley MKI or MKII thread diameter and pitch for two screws

[H Wally]

Hoping cgn can help out with some things, namely the thread diameter and pitch of two screws that I don't have, and are apparently unobtaneum. These are for a Webley MKI

Looking for the pitch/diameter of:

1) Barrel Catch Cross screw. The one that the barrel catch pivots on just in front of the hammer at the top/back of the frame. ( #31 on the print)

2) The Joint axis screw. The one that holds the axis pin in place from working its way out when you pivot the barrel open against the frame ( # 30 on the print)

And a very nice print/schematic of the MKI/II webley parts

Nothing eh? No one on cgn owns a webley and a thread gauge?

Sorry man, can't help you. I own a mk 2 but no thread gauge.

Likely a Whitworth, couldn't say for certain. Angle of them gives it away.

Valid point - had forgotten they weren't using our standard threading back then.
