Be a brave/foolhardy person that would attempt this,
given the vast range of things that BSA put over over the decades.
But B33 sounds like it might be something to do with a postwar 500cc single, in the frame dept at least. (?).
Quite how that sits with a flat tanker is anyones guess.
Its times like these a pic is worth a zillion words.....

Just to confound the issue too, in the 1920s BSA's little Model B was a 250cc 'Round Tank',
so thats not sounding very much of a match.
The Model A, which may be related to that engine number (?) was a little 2 stroke,
the predecessor (sort of) to the later bantam.

Are we getting warmer ?
Even a description of the type of engine, gearbox, wheels, brakes, gearbox, colours etc will assist to narrow it down.

Hi,
Post a picture of the bike and you will do better in identifying it
Dummy rim brakes on BSA were fitted up to the the 1926 models, 27 went to drum brakes
The 250's would seem to be ruled out as they went from "round tank" with rim brakes to drum brake and wedge tank for 27
There should be a letter prefix on the engine
