A Brief History of the Marque

1927 to c1936
Etablissements Omer Samyn
1 rue Ambroise-Thomas
ARGENTEUIL (Seine-et-Oise) 

Established in 1918 in Argentuil to convert American Liberty trucks which had been imported in their thousands towards the end of WWI and after the armistice, the firm presented their first motorcycles at the Paris Show late in 1927, with production starting in earnest the following year.

Initially these were 173cc two-strokes, and towards the end of 1928 246cc models were added to the range, the CS and the CS3, the latter with a top speed of 90 kh/h. Drum brakes were fitted to these in 1929, and the robust machines had QD wheels.

O.S.A. also produced models fitted with 346cc and 490cc JAP engines built under licence by Staub.
