New Member, identification help needed

[cormanzai]

Hi, so I am trying to help my great uncle identify his BSA Bantam model and year of production for a restoration project.

He is passionate about bikes and has been trying to get more info on his beloved Bantam, it would mean the world if someone could point me in the right direction (I don't know where to start other than this:http://classicenglishbikes.com/tech_file/bsa.html - but it does not tell me much), or give me any info on the following Frame no. bike:

WM20.107130,

any and all info would be so welcome! I think it would make his year if I am able to help him.

Many thanks in advance to all you Bantam heads out there!

Do you have any pics? If that's the frame number it would match to a 1943 M20 which is rather different from a Bantam being a 500cc sidevalve....
