TRIUMPH PART NUMBER SYSTEM
Triumph Part Number Conversion: In 1973 Triumph introduced a numerical part numbering system which superseded the old alpha-numeric system. For these earlier models the following information will help to find the new number. Prefix letters have been converted to numeric prefixes, as shown in the table below. We use a plain dash - to separate part number fields.
Alpha-numeric converts Example:
Dxxxx converts to 60-xxxx D4250 to 60-4250
Exxxx converts to 70-xxxx E4576 to 70-4576
Exxxx converts to 71-xxxx E12599 to 71-2599
Fxxxx converts to 82-xxxx F9356 to 82-9356
Fxxxx converts to 83-xxxx F13245 to 83-3245
Hxxxx converts to 97-xxxx H2091 to 97-2091
Sxxxx converts to 21-xxxx S413 to 21-0413
Txxxx converts to 57-xxxx T1435 to 57-1435
Wxxxx converts to 37-xxxx W354 to 37-0354
BSA PART NUMBER SYSTEM

Prior to this BSA used two other part number formats, the early system used less than six digits & requires zero's to added. The later system then preceded the original number with additional codes. With these numbers only the last six digits are used. We use a plain dash - to separate part number fields. For exmaple:
