I am new here but I thought I would give this friendly forum a go for identifying a frame. I got it from the original owner and it was supposedly competed on in 1968 and then unfortunately made into a commuter bike with mudguards. It was therefore drilled in several places. However, it is a nice frame and the other frame I got from this owner was a late sixties Pogliaghi frame so I do have some hopes for this one although not expecting anything like the Pog.
So the details and numbers…
Bottom bracket threading is British. Nervex lugs. Campagnolo dropouts. Double plated fork crown. A noticeable feature is the diamond on the seat stay caps.
The serial number which is stamped on the side of the seat lug in very small numbers read 73930 or maybe 73 º30
There is a “2” stamped on the steerer. Seat post size is 27 mm.
Ok what did I forget?
Not that much to go on but with so much expertise here I thought it worth a shot. Many thanks for reading.
