This is one of my favorites. Unfortunately,nothing is known about the set other than the year is the same as the retirement of the man responsible for the design/manufacture of the fed!

The serial numbers are:
Camera 44175(sandblast finished trudkomuna)called a FED b
right angle finder 2404 called a FED 10
Auto Portrait (sand blast finish marked trudkomuma)strange SN (backwards E)-20 called a FED 16
Macro lens (none not even on the lens block) called a FED 19
Meter NSN hand written scale called a FED 15
cable release called a FED 34
filters called a FED 11(macro)13(lt yellow)19(uv?)
clamp pod called a FED 33
Plates are all hand shaped(still have file marks on edges) and hand engraved

Speculation: It is a FED b because it has the accessory shoe!
