For 18 months I have wondered how old my BSA is.
I have posted on it before, then followed a mild forum debate on 'what is a Path-racer?'.
The 3 numbers stamped on the frame are easy to read, but there is no database of BSA serial numbers that I can find.
I have always thought it was 1920s, but with no strong evidence. I did come across a comment on the net that BSA had gone away from bolt-on seat-stays by 1932, but there was no documented proof of this.
Then last night I stumbled on this fantastic site - http://bsamuseum.wordpress.com/
the photos and old BSA literature on this site have enabled me to narrow down my bike to approx late 1910s - end on World War 1
