With
their dad being a motorcycling "enthusiast" and their granddad
being a motorcycling pioneer, it really shouldn't be any surprise.
The picture of my dad is from the late 50s I believe, he's racing
his Puch at Westwood. Westwood is now a subdivision, but the Puch
has been restored and can be seen at the Trev Deeley motorcycle museum
on Boundary Road.
Take care.

Puch produced the "Twingle engine" which
is a small capacity two-stroke engine. It uses two pistons, one of
which controls the inlet
ports, the other the exhaust ports. These run in two parallel cylinder
bore but share a single combustion chamber, spark plug and cylinder
head.
In 1928 the company merged with Austro-Daimler and became a part of the
new Austro-Daimler-Puchwerke. This company in its turn merged in 1934 with
Steyr AG to form Steyr-Daimler-Puch. Like all enterprises of its kind,
the Puch production plants had to change to arms production during World
War II. The existing capacity was insufficient, therefore a second plant
was constructed and opened in 1941 in Thondorf, Graz. In the three original
assembly halls, luxury vehicles for the American market were produced.
