Frame no.

[HAYWARD]

Why cant I find a frame number on my 1939 B26. I have looked in all the usual places and found no trace of a number.

Why cant I find a frame number on my 1939 B26. I have looked in all the usual places and found no trace of a number.

Well, the reason that I can't find mine is because the frame has been powder coated and covered it up.

[HAYWARD]

Mines been shot blasted off, and I still can't find it!

[A10 JWO]

Shot blasting should not take it off at all. Mine has just been done and is clear as day. I masked over it before it was powder coated for all to see. I then sealed it with some of the wife's nail varnish.

[HAYWARD]

I just don't think it was on there to start with. The bike belonged to my dad, but I can't find any documentation except a hand written bill of sale from the chap he bought it from, and the petrol ration book with the reg. no. I have an engine no. but no frame no.

[GLENN]

Where all have you checked?

[HAYWARD]

I've looked everywhere, steering head, seat mount, top tube, even used a magnifying glass, but no number.

[GLENN]

I must admit that I've never closely examined a B26, but in 1939 BSA were stamping the frame number on a M20 on the front down tube, N/S at the top engine mounting bracket.  Later this was on the down tube, stamped into the casting close to the headstock. 

[HAYWARD]

Not there either, looked everywhere.

[GLENN]

Well if everywhere has been checked then it just must not be present.  Perhaps a replacement frame has been fitted with no number stamped, or the number has been ground/sanded/blasted off?
