A Brief History of the Marque: MAS
MAS (1920-1956)
MAS (Motocicli Alberico Seiling) was founded by Alberico Seiling, a
successful motorcycle designer. Early machines had 148cc, 173cc and 244cc
ohv and sv engines with pedalling gears and large outside flywheels. Production
in the 1930's concentrated on budget priced 248cc, 348cc and 568cc side
valves along with a luxury touring model with a 498cc ohv engine. Most
late '30's models offered rear suspension and all models had inclined cylinders.
During WWII, MAS supplied the Italian forces with 498cc ohv singles
and a 173cc two stroke. An innovative 122cc single, the Stella Alpina,
was introduced in the late '40's. It had a top end cast in the form of
two concentric cylinders with an inner cylinder joined to an outer cylinder
by a series of vertical fins. The theory behind it was that such a configuration
would keep the engine cool at low speeds. It was not a commercial success.
More conventional models in the '50's had 173cc ohv and ohc engines,
and an interesting 500cc ohc twin intended for racing never left the prototype
stage. Before the company folded, MAS was reduced to making utilitarian
124cc two strokes and a Sachs engined 49cc mini-scooter.
This venerable Milanese company closed its doors in 1956.
Hope this is useful ...

Additional notes:
There was also a Seiling brand of motorcycle, apparently, and another
financed by engine manufacturer Türkheimer, the Altea.
