Well, unless my Russian totally deserts me, the longer Russian word is a name - assuming it's not worn too badly, I'd say it read "
G. Malikov". Either the guy who made the lock, or possibly the one who inspected it, seem likely candidates.
On the British lock, I'd conjecture it's a government inspection mark. I'd suggest slinging this onto the British Militaria Forums (
http://britishmilitariaforums.yuku.com/directory) as well as here; the more the merrier, as they say.
