Universal got back to me at last.
Dave Marsh said he has been on holiday.
Regarding this frame he said:
Thank you for your enquiry on the Carlton frameset.
The frame and fork are Reynolds 531 double butted tubing , this is a rare early model with very nice lugs, the front and rear dropouts are Carlton own design but not forged , the eyelets are to take mudguard stays .
The seat tube measures 21" from the centre of the bottom bracket to the top of the seat lug, the top tube measures 21.5 " from centre to centre.
