ok, so i am trying to figure out what BSA my pop had when he was younger.

all i know for sure is that he said it was a red 500cc, overhead, and also i'm sure he said it was a single. He lived in victoria & sydney, didn't have a lot of money, and would of had it between 1943-1958, but he may have bought an older bike too.
Thats all he managed to remember before his passing recently.

so i figured with that information it would be one of these:

any help at all, or any idea's on how i could get it narrowed down would be greatly appreciated.

Hi, It wont be one of the Ms as they were mainly sidevalves or in the case of the M24 expensive. If red could be maroon then I would suggest it would have been a B33, otherwise cant help.I am mainly a 50s onwards but I am sure there are others more knowledgable. Google is a great help and there are sites that tell you just about everything you need to know.

Has MA got records and a data base ? When we buy a comp. licence they must spend the money somehow.

Is your machine authentic or merely eligible?
