Triumph Austin 4 ca 1932 750 cc four cylinder side valve frame#808576
“ If they wont list one, I’ll build one myself” could have been the motto of the designer and builder of this remarkable Triumph.
Or should we call it a Traustin?
It was created by Chris Shorrock who was a successful manufacturer of superchargers.
He was well known and many of his superchargers were used by manufacturers of high powered racing and sports cars.
Shorrock superchargers were also available to private buyers, though.
The conversion was carried out in the thirties.
The cycle parts are probably CTT Triumph.
The machine has been restored with care.
