Fa 41 nm


I was cleaning up and came across following Technical Manual

on page 48, it became interesting

Does anybody know how these TMs were made.
Are this pictures or drawings ?





I believe that HWS says that they (probably Col. Hackley) examined a photograph of a FA 41 NM that was used to illustrate TM 9-1190. Your post shows what appears to be a half-tone of the cartridge so that tends to confirm that the cartridge did exist and that it was photographed.

But, the big question is - what happened to the FA 41 NM cases?
