My Record Sprints (I had two, circa 1984) both had Helicomatic hubs - and Weinmann Concave rims.
I put a lot of miles on them, but with the benefit of hindsight, I wouldn't recommend putting much effort into one these days. There are much nicer bikes around that justify the trouble. I broke just about everything that could be broken on mine, including both frames.
Not a Record Sprint, but I used to have a secondhand Raleigh Quasar of similar vintage, which had the same Weinmann/Helicomatic wheel combo. The Record Sprint had a very similar spec except for external brake cables ("aero" levers were a new thing at the time it was made), Sachs Rival friction derailleur in later years at least (the Quasar had a Suntour AR mech) and so much gold anodising that it was the bike world's answer to Ron Atkinson
. The "aerospace contour" Reynolds 501 frames apparently had a bit of a reputation for dodgy quality, but other than the top tube cable guides dislodging mine put in many, many miles without dropping to bits.
Brian - as for the tyres, cheap-ish 700c x 23s should see you OK for general pootling around. Seem to be some decent internet offers on pairs of Michelin Speediums out there at present.
