Fake? / Indentification Help

[Lapa]

Phillip,

Only the size differs. The small variation (very common) is as you described, pinback attached. The large variation (from memory it measures about 4cm in diameter) has a screwback fixation, and is very scarce, probably issued in the low hundreds. It is said that these large ones were a special order from the city of Moscow to be presented to specific people.

I can't say more than that at this time. I'll have to try and locate my large one (it is very safely put away somewhere, I know it, but where :()
