A Brief History of the Marque
81 bis, Boulevard de la Republique, La Garenne-Colombes (Seine)
Manufactured 1924-1925 and possibly later.
A 1924 Paris Salon issue of a French magazine and a 1925 issue of Motocyclisme magazine included Baggi-Samyn, listed as having a two-stroke LMP engine with 52x58 bore/stroke, a two-speed Picard gearbox with kickstarter, and belt drive.
An advertisement from the same period lists two machines, one with a 250cc Moser and the other with a 350cc LMP engine, both fitted with a Burman gearbox. It also mentions that they employ Blackburne and J.A.P. engines.
