nice pics here from a previous thread:
http://www.vintagebike.co.uk/Bike%20...ti%20Index.htm Just had a look through Ian Falloon's restoration guide (isbn 0-7603-0697-4)
Seem the very first 500's were gold wheels with polished rims, going to full gold by 1981.
FPS & Oscam wheels are mentioned for 1983 but both in gold.
There is a ;istin gof colour schemes for different year models if you'd like me to type it up for you.
Good luck - Frank
