Norton International 348cc. OHC – 1934 England GB.

The Norton Inter story started as far back as 1927, when Walter Moore (formerly the Douglas chief designer) created the first Norton overhead camshaft engine with bore and stroke dimensions of 79×100 mm, giving 490 cc capacity.
Straight from the drawing board it provided Alec Bennett with a TT victory in 1927.
Known as the CS 1 (Camshaft Senior one) it was listed as a production machine for the 1928 season.
The smaller 348 cc version ( 71×85 mm) was known as the CJ (Camshaft Junior).
By 1930 Moore had left to work for NSU in Germany and for the TT that year Arthur Carroll , his successor at Bracebridge Street, redesigned the camshaft engine.
With this design Norton started its incredible run of success in road racing.
For the 1932 season two types of road going race replicas were listed as the “ International” in 348cc and 490 cc capacities.
