I saw that on Ebay, and actually asked the seller if it was his from new as I was thinking it should be 653. He did say that it was his uncles (or similar) who owned it from new, and that it was original. It looks like a Raleigh (lugs, fork crown etc), but it's unusual not to have any frame number.
Suppose the odd one slipped through the net!
Yes it was an ebay whim that I couldnt really afford but this pic sold it to me. Luckily it all polished up as well as I hoped!
Everything but the chrome taper nut on the brake spindle. Are these nuts still available?
