NORTON PART NUMBERS:
The pre-Commando part number system can be tricky and it may be best to use the alphabetical section of the price list.
Most Commando parts begin with either 06-XXXX or 04-XXXX & are then followed by a further 4 digits, e.g. 06-3371.
|BSA PART NUMBERS: From the mid sixties onwards, BSA adopted a standard numbering sequence which follows the pattern of 2 digits, a dash, then followed by a further 4 digits, e.g. 71-2790. Prior to this, BSA used two other part number formats. The early system used less than six digits and 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.|
