Notes on Triumph engine and frame numbers, 1915 to 1923.

1. Civilian frames begin at 301978

2. From 1915 to 1923 some engine numbers were followed by a three letter code.
These relate to a dating code by which the month and year of manufacture can be identified.
This code does not apply after 1923. The code is as follows:

T R I U M P H C O D E X
1 2 3 4 5 6 7 8 9 10 11 12

Example: A ‘UTP’ prefix (or suffix) would translate as 4/16 or April 1916.
