The original smg uses a conventional wooden stock as the later one uses a more compact configuration,more info on this weapon is needed.

Cool,
Very P90, what's old is now new.  Retro has made a conceptual comeback in some circles with idea of a reliable/accurate weapon,  pencil barrel and less than 7 pound weight. As opposed to the Mod concept to hang any conceivable contraption on a carbine until the weight falls somewhere between a M249 and M240. This idea was clearly ahead of its time, I hadn't heard of it , so THANKS!

If I remember right there is a write up in Submachineguns of the world Vol I on this item....

It's interesting how the prototype in army photo used an MP40 barrel assy.

the cartridge movement happens in the action.... probably thought to be a weakness for dirt to jam up the works...
I believe the P90 moves cartrige in the magizine head and not the action like the hill does...
