After a quick glance, I confirm what I have already written:
- brass shutter crates up to s/n c. 115000,
- alloy up to the end of 1e series,
- brass for my personal NKAP Red Flag,
- brass for the 1f series, up to 250000,
- alloy after.
Note that the limits are those I observe on my personal cameras. And certainly, there could be mixed parts, specially after WW2.
Thanks Jacques,
so you check only the bottom plate of the shutter crate, right.
Strange, so my #182393 could be a fake which I doubt, could be postwar which I doubt too, and my #221333 is also a mystery. Both I got very cheap

We need more samples for brass and alloy crates in the serial range #170.000 till #250.000 please.
