The FACH used American M1 helmets, and this helmet is not of that origin. And of the European clones, it only used two, and they are from Western Germany: one is the M56 and another is a helmet type M-1C, made by SW, and manufactured for the export only and never used in Europe.
I'm back on the hunt to identify this Chilean M-1 shell. From what this quote indictes, the shell can be narrowed down to two West German shells. Now the question is, how can these two shells be differentiated from one another? Any suggestions?
