BSAOC 1997, 1998, 1999, 2000. All rights reserved.

Pre 1929 markings are based on listings available to the Club but do NOT have any form of cross referencing, therefore there is no way of checking their accuracy. Post 1929, the listing are cross referenced by the despatch books and by contemporary listings in parts books and dealer service sheets, where available. This cross referencing is available for most models up to the closure of the factory. However we are currently revising the pre 1929 lists which we are cross referencing with machine which we have personally scrutinised and verified. We need your assistance to help us on this and request that anybody who has pre 1929 BSA bikes write to the machine dating officer Brian Pollitt (address below) with details of your machine and photos of the complete bike plus detailed photos of the engine. All photos will be returned. BSAOC pre1929 Machine Dating, Brian Pollitt, 16 Dane Avenue, Partington, Manchester, M31 4GB, UK
