Generic and very common BB shell for that time I think I recall...
I think my La Variable has the exact same one and number, which means it's just the model number of that BB shell

That explains it thanks.
Any idea on the underside lugs and reason /use? -
Similar.
They both could be from Vaughan's in Birmingham, @anidel yours definitely is.

BB is rather interesting as it has these raised lugs on both sides (Drive side with the most) but from the 49' it would appear that these frames were fixed, So maybe a later modification at some point in its 72 years.
Frame No 7740 which makes it 47'.
Research shows production that year ran from No 7150 to 8500.
Underneath the the frame No is CR 23
(C could also be a G ) and looking at frame builders who worked for Holdsworth at this time could mean that this stamp means that the frame was made by Charlie Roberts, Father of Chas Roberts but I'm not certain of this
