Factory ?? I.M.G?

Doc AV

Thank You Doc,
I think it was an I, but it was nicked up.
If it is an F, then it would be from Chili, correct? (Fábricas y Maestranzas del Ejército de Chile.) Do we know if both factory’s used the Roman date?

I agree with Doc Av. It is “IMG” and from Industrias Militares de Guatemala. The form for the name he used may well be correct, but I have always seen it as I typed it. My Spanish is not so good. I don’t collect 5.56, but seems to me when this was being imported into the USA, that I saw the Roman dates on some of the headstamps. I have never seen them on a Chilean or Peruvian cartridge.

Chile uses “FAMAE” and Perú “FAME” usually, although not exclusively. Guess it depends on when the cartridges were made.

Great, Thanks!
