Chevrolets did indeed have chassis numbers from trhe beginning, and are easily decodable except that assembled Holden, GM NZ and GM SA chassis were allocated numbers which included a plant code, and they had a different series to that of Oshawa plant.

Fords used the engine number throughout but in 1941 I think it was used a chassis number of sorts. Henry decried the use of chassis numbers, as States used engine numbers until 1955. However the model number (Ford) and official designation on the build plate was the identifier.
