Steve, did you click on the link I posted?
I've just been back and had a look again myself. The 'W' part of the code means it was made in Worksop (although if it was made after 1981 when the Worksop factory closed, it was actually made in Nottingham), and the 'M' means in September.
The '3' refers to the year of the decade it was built in, so presumably either 1973 or 1983. What components does it have on it? Who made the chainrings, brakes, derailleurs, cranks etc? Given the brainpower and knowledge on here, it should be pretty easy to work out which decade it's from.
And I think the last bit means it was the 1959th model off the production line that month. Although I don't know if that would mean it was the 1959th of its type, or off the production line per se
.Here's a picture of a 1983 Raleigh Clubman
that I found via Google just now. Is this anything like yours?
Keith, I'm fairly new to all this having bought an '86 Raleigh Competition a few months ago (and welcome a correction if I'm wrong...) but it's my understanding that although Raleigh did produce millions of 'racers' made from mass-produced gas pipe frames of dubious quality, their Lightweights of that era were handbuilt in the factory. And from what I remember having read, I'm fairly sure that a Clubman was actually the level between Raleigh's range of commercially-available lightweight bikes made from Reynolds tubing, and their 'professional' range.
1987 Peugeot Tradition (3-speed Sturmey Archer)
1984 Raleigh Classic 15 (Reynolds 531 ST)
1970s Harry Hall (Reynolds 531)
1986 Raleigh Record Ace (Reynolds 531)
and a project involving two Raleigh Record Sprints and the 531 frame from a 1990s Raleigh Quasar...
