Hello All I have a 23 inch ctt with a 221/2 top tube ctc Bob Jackson frame set for sale. I am guessing that it is 1960s (?) . the frame # is 7838 and used Prugnat lugs with Campag ends. It has round fork blades and a slotted crown. It is also fitted with a q/r rear brake stop on the seat lug. The paint is original but now very tatty. I have pics available and is well worth a look 100 GBP plus post Regards Pete Paine Watford
