I'm new on here, so please be gentle. I'm trying to identify a frame I have recently been given by an old friend who has sadly given up cycling through ill-health. I've stripped the frame of parts and taken off most of the old paint. It's now in primer. The frame had Dave Marsh transfers on when I got it. (Dave Marsh has been building frames for many years, having started as a frame builder for Carlton cycles in Worksop, England). He's still in business, near Rotherham, in South Yorkshire. I sent Dave photos of the frame together with the frame number to see if he could identify the age and frame tubing.
Dave was very helpful - he's a lovely chap - but came back to say that the frame wasn't one he'd built, but had most likely re-painted in the past. He suggested the lugs are cast Italian (the seat lug arrangement is very reminiscent of a Masi) and the forks have the word LUNGI (Italian for "long") stamped onto the steerer tube, but there is no other indication as to what tubing has been used and no frame tubing decal anywhere. The seat tube is 21.5 inches centre to centre. The head tube lugs have 73 and 61 stamped onto them, the seat tube lug has the number 735 (raised, not stamped), as if it was cast into it.
The frame number is stamped under the bottom bracket, but some of the numbers are very faint. As best I can make out, the numbers appear to be T5 06 01 64 (although the numbers could be T5 0? 21 64). Both the fork and the bottom bracket have a stamping that looks a little like the side view of a drop handlebar followed by a 0 that is elongated and slopes forward. They are quite faint, so would not show in a photograph.
The seat stays are pencil thin with a "scalloped" top eye. The frame and forks have mudguard eyes and a lot of clearance for mudguards. The rear dropouts have holes for adjusters, but no adjusters are present. Neither fork ends or dropouts have any markings, but are obviously decent quality cast items.
Some photos are below.
The bike was purchased second hand a good few years ago by my friend from a local bike store in Doncaster, England. The store rebuilt the bike using a used frame they had in stock and built it from used parts (mainly Suntour). The frame is still in remarkably good condition, confirmed when I stripped the paint off.
If anyone has any ideas as to what the frame might be, do please let me know. It has been suggested that it might even be a Masi frame (although it doesn't have the typical Masi cutout under the b/b shell). Here's a long shot. Tom Simpson was originally from north Nottinghamshire/South Yorkshire. When he rode professionally for Peugeot in the 1960s, his racing frames were made by Masi, but painted in Peugeot Team colours. Wouldn't it just be nice to find that this was once a winter training bike ridden by Tom (my boyhood hero)? I know, but stranger things have happened!
