Engine & frame numbers for Triumph single cylinder vintage motorcycles including the following models, 3HW, 3SW, 5SW.
I have compiled a series of tables to show the generally accepted information on the engine and frame numbers for Triumph motorcycles. This table shows data specifically for the Triumph single cylinder motorcycles from 1939 to 1945. To be fair, this isn’t the most detailed table, but this is all the information I have. I don’t think they were too bothered about sequential engine and frame numbers at the time.
