Hello @polman. To be honest I can’t find any reference of the MUSA headstamp right now but I can tell you for sure DIM means Dirección de la Industria Militar, which in englishs would be Military Industry Headquarters. However I will look into the first photos.

So all of these are military? Did Mexico field shot guns?

“MUSA” was made by Manufacturera Universal, S.A., Distrito Federal*. it was established in 1940 and dissolved in 1946. Between 1945-46 it was mostly owned by a US company named Hunter Mfg. Co. of Bristol, Pennsylvania, who during WW2 loaded 20 mm cartridges and artillery shells.

“DIM” stand for Departamento de la Industria Militar, Tecamachalco, Distrito Federal*. It was established in 1918 but this designation was used since 1947. It was briefly known as Dirección de la Industria Militar in 1946-47.

*Since 2016 renamed Mexico City (Ciudad de México).

They were made for the civilian market.
