1930 S.O.S Sales Catalogue.

Not a well known manufacturer, SOS (which stands for Super Onslow Special) first appeared in 1927 but never survived past 1939, most likely to the drain of WW2 on resources and materials. Most machines were powered by Villiers 2 stroke engines with a few by JAP 4 stroke singles, there was also a water cooled version. This catalogue from 1930 would quite unique as it was right in the middle of the depression so there would have been very little money for anything. It has 4 models, the Villiers engined Model C and the Super K, the 246cc 4 stroke JAP powered G.S.1, and the 346cc 4 stroke JAP powered G.S.2.
