A gentleman posted this today on one of the Moto Guzzi forums I frequent. Very interesting...

Found this yesterday, there's a little museum Berlin Alexanderplatz, wasn't looking for it just stumbled into it.
interesting V twin, whether this was a prototype, factory job or something an enthusiast built I cant say? Seems a flat twin and V twin were built along similar lines (looks a bit like 2 x ETZ250 block/heads?) but only the flat was exhibited in a motorcycle.
