Piccoli is an Italian surname that also means “smalls”. Piccoli Motori was near Bologna Italy, but is not in the Wheels of Italy Encyclopedia. Baretta is a trade name made up by Baretta of America, 2904 S Figueroa Av, Los Angeles California. The spelling of “Baretta” is that of the 1970’s TV series, with an Italian detective, not the “Beretta” hand gun. The Piccoli-made top tank chassis, Baretta Magnum and Cosmo Colt 1 and 5 are the same. The Piccoli-made step thru chassis Baretta 22, 38 and Cosmo Blazer 1 and 2, are all the same. The Piccoli-made monotrave chassis Baretta 44/45 is close to the Lem Pratikal, but the Lem rear lifting handle is straight, while the Piccoli is curved. The Baretta 44 has spoke wheels and a solo seat. The Baretta 45 has Grimeca “snowflake” mag wheels and a long seat.
The Baretta and Malaguti floorboards look the same. The only difference is the bulge for the V1 or MO-1 start lever. Also the Cosmo Colt floorboard is like these, but with a different carb hole location. Piccoli probably made them, since that was their business.
