I'm having a hard time deciding exactly what this is - a Raleigh / Carlton of some kind I think - the BB frame # of "DD 136" suggests its a 1969 going by Kurt's published codes - but that's the only code on the BB - or the frame for that matter.
It has Campy dropouts but no chroming - and no decals for id, apart from the Reynolds ones - which do incidentally look original, but I'd be more definite about the originality of the paintwork (lagoon blue possibly?). Lugwork detail is nice but not overfancy as on some of the later professionals I've seen....
Any ideas? Your advice and input will be greatly appreciated - TIA!
