'20' is the model code for the 750 Atlas, and 120693 is from early 1967 according to UK NOC data. GRM 450 said: 650 Atlas? motor # 20/122282/P Click to expand... The Atlas was always a 750. '122282' is also from 1967, but frame and engine numbers would have matched originally. Nortons were built at the AMC (AJS-Matchless) works in Plumstead Road, Woolwich, London SE18 from 1963-68, so engines have a 'P' (Plumstead) suffix.
