This is a Zundapp (borrowed internet pic, not my dad's). There are also quite a few other things that are Zundapps, like most of the WWII German sidecars that everyone calls BMW's.
Their war models were about as different from a BMW as a Buick is from a Chevy.
German company, started out making hand grenade detonators during WW1 and then into motorcycles and cars and sewing machines. The Zundapp logo is actually a bomb fuse.
They made dirt bikes, were very successful in Grand Prix racing with the smaller classes and eventually sold off corporate rights to India and China where their small moped things are probably still made.
From all reports, they were actually quite good bikes for their time.
