To whom might be able to give guidance. I am thinking of selling my bike that I restored many years ago. The original title and current title state that it is a 1968 year model. All the parts on the bike at the time of restoration were/are 1966 components - tail light, side covers, basically everything about the bike. The engine cases where replaced many years ago and have no serial number on them. Someone in the past had stated that it was not uncommon for BSA to sell left over units as "newer" year models. Could this have been the case? All I have to go by is the frame # A50C4115. Any feedback would be greatly appreciatated. Thanks in advance.

The BSA Owners Club in the UK has a copy of the factory despatch records, and will provide a dating certificate for a modest fee.

The VMCC in the UK also has a copy of the factory records. Members can have the library search for the records of 2 machines free each year. Unfortunately, their operations are very severely curtailed at present.

The BSAOC and Britbike also have online summaries of engine and frame numbers by year. This is enough to get into the right general area, which is enough for most of us most of the time.

As Rich noted above, A50C frame numbers were only used for the 1966 model year. Early 1966 frames were stamped A50C, but later in the season BSA switched to matching engine and frame numbers.

There is scope for endless distraction in those dispatch records.

i read some where , probably right here on BritBike
that #3217 is the first matching number 650 recorded in the dispatch books .
( still searching for the quote )
does the first matching mean the last non matching ? ... i would think so , but you never know

1966 was very messy year for BSA .
4000 twins were shipped from the US , back the the UK ... to have various problems remedied .

Prior to that, the frame number is different than the engine number, but a "matching number machine" would have the correct specific numbers for each, as they came off the production line . . .
