I don’t care what anyone says about the scooter, this is solid.
Looks like a 90mm recoilless rifle on the Vespa. The postwar Italian army was equipped with U.S. weaponry and since the 90mm was tripod mounted & portable this would have probably worked. On enemy trucks, I guess.
A volley formation of weaponized Vespas could have been formidable. Not quite Rat Patrol, though.
It would take some big solid balls to fire that.
And you might be walking funny for a while, ouch.
Just what I need for rush hour traffic.
