Hi Paul.I always use the Brickwood Rim Company in Hampshire...
They can supply Devon Rim Company rims which I think are the best quality..I've just had my M20 rearwheel done by them with an unplated DRC rim...
They are also currently doing the wheels, with alloy rims, for my sprinter...
You'll find their details on Google...(IMHO avoid Central Wheel Company if you want quality rims)...Ian
I have just had my M20 wheels re-spoked by Brickwood wheels and they did a nice job and at what i thought was a reasonable price .there phone number is 01722 712701. Jeff
If you contact the Devon Rim company directly they will spoke their rims. Over the years I have had 5-6 sets done and all a first class job. They also used to paint the hubs and centre line the rims if needed. I would also rate their rims the best.
