Ha, ha!
This part of wikipedia is much better, though not perfect:
https://en.wikipedia.org/wiki/FED_%28camera%29Another Fed 1e, here. The s/n 183613, one of the last ones.
The date inside is 16/X or 16/XI, so after the evacuation. Could it be a "real" Berdsk? It's a pity we don't have the dates of control for the very last 1e-s, up to c. 184000, as it seems.
Of course, there can be other explanations: repair, re-mounting with other parts, etc.
Something else interesting: the lens is a collapsible macro, s/n 2121. But is it the original one? I don't know.
