I have a very original 2 owner 1952 Comet with less than 20k on the clock which appears to be correct. I am starting a sympathetic restoration intending to keep it as original as possible. One of the main things I need to do is to have the wheels rebuilt. It is currently fitted with a "Trade Dunlop" WM2-19 front wheel rim and a "Trade Dunlop Mark" WM3-18 rear wheel rim. The "Original Vincent Motorcycle" shows that these wheels should be 3X20in front and 3.50X19in rear. Please can anyone advise? ps the wheels are currently fitted with ancient Avon Speedmaster Mk2 tyres 3X19 and 4X18
