VOILA!!! Thanks Hilary. I got out my digital calipers and measured the toptube and seattube of the Team Pro versus a 1969 Raleigh Pro and a 1974 Raleigh Competition, both of which can safely be assumed to be English gauge 531. Metric tubing should have a 0.6 mm larger toptube and 0.6 smaller seattube. Measuring to tenths of a mm is tricky, but the Team Pro toptube is indeed about half a mm larger and its seattube about half a mm smaller.

So let me ask the converse. Does metric gauge tubing and a 26.8 seattube definitively indicate 753?

Also, does metric tubing help date the frame?

The one I picked up yesterday that had been Ebay.co.uk I think dates from 1978 or so and has a 27.0mm pin. I am not quite certain when Reynolds started manufacturing Imperial sized 753 tubing - I should think it was around 1980/1. Imperial sized tubing 753 should really be 27.4 but may be 27.2 on some frames.
