...I got this last year, and couldn't figure out whether I wanted to paint it or not, so it hung around for a while.
The paint job is not as nice as the original flamboyant green, but the original had a lot of chips and scrapes/scratches. It was impossible to touch up, I tried.

I think it's from about 1971, came with a 54/44 Campy crank in the old 151 BCD standard, and the owner had replaced the original Weinmann CP brakes with Campy side pulls.

I had some brakes around that are relatively correct, and IMO, the 144 BCD cranks look similar enough to the original. I did stick with the record derailleurs.
Rides about as well as anything else I've ridden from the very early 70's, and reminds me a lot of a Bob Jackson I had from about the same year. Very British.

...this is what the frame looked like when I first dismantled it for cleaning.
It was in pretty good shape, as you can see. But there was a lot of variable fading overall, and the aforementioned scrapes/scratches.

Anyway, I took a deep breath, mustered up some courage, and decided to paint it. Maybe some day someone will completely strip it and try to reapply the original flamboyant green.

Very nice intake; thanks for posting.

1971 a somewhat late date for 151BCD. makes me wonder if birthday perhaps a bit earlier. alternately the chainset worn at intake may not have been original. 151BCD a good temporal fit with the Record rear mech.

have you identified original HS? it is not the usual Alatet so often fitted. appears Thomas D. Cross Continental Prima.

....I was just going by the serial number on the frame, Y 7936. The guy I bought it from liked to tinker with his bikes, so I'm not sure the parts it came with are much help.

The wheels it came with were less than admirable, and I did not find the side pull brakes to be especially appropriate to the bicycle. The Wayback machine link to Carlton dating would put a Y serial number at 1967, but the serial number is stamped on the BB shell, not on the rear dropout, so I'm not sure this is correct. Anyway, somewhere in or around the late 60's/early 70's is good enough for me.

I wanted to use that old crank, but there's no way I could push a 54 chainring any more. Not sure I ever could.

Wow, the starting point was so much better than my 1967 example, which looks just like the two examples above in terms of details. Mine is a kind of rootbeer brown, but the chrome on the forks is mostly nail polish these days. I told myself about 7 years ago that I'd get it rechromed and do a professional refinish, and build it up as a touring bike, but haven't bothered yet.

Can the Campy sidepulls reach a 700c rim? I tried, and couldn't get the rear to reach. It would probably have been okay with a 27" rim. I eventually switched to Paul's Racer centerpulls, so I've got a $300 brakeset on a fixed gear bike...

...no. The way he got them to work was by rebuilding the wheels with some 27" rims that didn't have much in the way of a bead hook.
