The Hotchkiss Universal is a pretty interesting submachine gun, despite its rather clumsy appearance. The overriding design intent was to make a very compact folding carbine, and Hotchkiss certainly met that objective. However, the gun ended up being too expensive and complex to achieve any real commercial success. Some wound up in Indochina, and some sales were made to Venezuela and Morocco, but that was about the extent of the Universal's production. There are a few of these guns that were imported into the US as live semi-auto carbines, interestingly.
