Claud Butler Frame Identification

[wonkytoad]

Hi all

Trying to ID and date a CB frame. Have no information about it's origins.

Frame number is 30959 stamped on underside of the bottom bracket, and the same on the steerer. (no additional numbers on steerer tube)

I was thinking it was an Electron but they seem to have straight rear brake bridges, whereas this has a curved one.

Any CB experts can give me any clues or pointers.

Will try and get some better photos tomorrow.

Thanks

BTW id did have pump mounts on the top tube, but both we're broken so I have cut short and filed.

Head badge was black and silver rather than multi-colour as most seem to be, although I need to look again and see if it's been painted, as the whole frame was badly handpainted.

From memory it looks likes a Holdsworthy from about 1960.

Re:

I've got an Electron with a curved rear brake bridge, so don't rule it out! The Prugnat lugs look right (althought I think they were used on several CB / Holdsworth models). If I remember rightly, my Electron is 1967 or thereabouts. I'll check the serial number and date tomorrow.
