Could this be an FB on the frame? If so it looks like both frame and motor are 1958 right.... ? And I thought only gold star frames had the dented frame at the bottom

All pre-unit B & M singles had the notch in the frame to clear the oil pump. Since all were based on the pre-war M series, they retained that feature to the end.

All of the B series have the kink in the frame. Looks like you have a very early 1958 which will have the first alternator for electrics. That is a strange ‘F’!, but is what it should be.

The lack of a kink in the frame identifies the frame as having a Twin engine fitted.

Hi Wade----those are not very common in US--at least not in the north east IME.
I picked one up a few years ago in northern NJ.
It is a bit of a bitsa--the frame number is EB31 84** which I think means the frame is a 1956 or 1957---probably the latter.
The engine is GB33 5** which I think means it is a 1958.
It has alternator electrics and is fitted with a QPD primary belt drive.
I had a hell of a job getting an outer primary cover---one with the saucepan shape to cover the alternator--but eventually got one from Draganfly in UK.

It looks a bit like there wasn't an 'F' stamp available, requiring a bit of creativity.

The engine number is quite low and so is the frame number, so it would have been built very early in the model run. Wade will need aside trip at the BSA International to visit the VMCC library at Burton on Trent.

So its quite possibly a matching engine and frame.... Previous owner wasnt sure but said its the pair that came to him..... Ill have to layout all the boxes to see whats there and whats not.... No fenders and no seat is all I know for sure at this point.

VMCC library sounds great thumbsup

I'm a member, but you don't have to be to visit the library and go through the records.
I've already lined up a day there with my list of engine and frame numbers while Cheryl goes off doing touristy things.
The head librarian seems a rather nice woman, and has been very helpful so far.

From the dispatch book

"The numbers match, it was dispatched from The BSA factory on 30/11/1957 to Bsa inc (I think) which is East coast. It’s model is stated as B33B"


What does B33B mean?? Special trim ....base model..?
