Mike,
These sound like 597mm rims, which were highly regarded but which fell out of favor for some reason. If that is what you have, Very few choices exist, even in the UK. You might try St. John's Street Cyclery:

or Harris, in the US:

BTW, since you're British, and have some real knowledge of circa 1960s bicycles, did you have any experience with the lightweight, stainless steel Dunlop rims? If so, what are the tricks one needs to know, relating to building up reliable wheels using them? Best regards, Fred Rednor - Arlington, Virginia (USA)
