What is this?

Here is to add to controversy:
First shoot is case for FED-1 s/n 227818 build right after the WW2(?).It has very rough but strong MDF king board. Most definitely board is original and it unusable for writing notes. Probably plastic was in short supply at that time. So FED definitely put it to stiffen the case and protect camera.



Second picture is from FED 2a case. It also has such packet, but FED-2 had cast aluminum back and do not need any protection from behind . So board most definitely was intended for writing notes.



So it was for both uses!!! While I strongly believe original intention was to protect camera. I believe manuals said this board is for notes because it would not be a good busines to admit that camera is not strong enough.

This FED #307045 has it as a 3mm thick black cardboard: not good for any other use than extra protection?

BTW I did buy it as it was only 13 euros... But isn't the lens with "old f-stops" too old for it?

Great find!!! ans specially for 13e
Is it flash accessory or is it selftimer on the camera?

It is the flash syncroniser, there is another topic for that here
