The French Hotchkiss SMG.

[RCS]

I found some data on the Hotchkiss "Type Universal" submachine gun. It was designed and manufactured by Hotchkiss in Paris in 1949, being intended as a semi auto police weapon later modified to full auto, it has
undergone a number of design changes (example Type 010 and Type 017). Used in early fighting in Indochina and Venezuela has purchased them in the 1950's.
