[Update: Detlev thinks, its a souped up Scorpion, like the on on the right had picture. That would mean, it fires Modell 61: 7,65 x 17 mm HR Browning,
Modell 64: 9 x 17 mm Browning, Modell 65: 9,2 x 18 mm Makarow, Modell 68: 9 mm Parabellum. Is he right?]
Who wants to write up some stats and a description for this gun? Can it be cyberlinked?

To me it looks like a souped up Scorpion MP. You can take the stats from the “2020” and give them a work over with Blackhand’s Handbook. Checking out Wikipedia on the Scorpion can give you ideas for alternative amunition.
its a MP5.
with some very very nice engraving.
