The only firm I know of who can work with wire wheels is Hendrix Wire Wheel of Greensboro, NC. Allen does a GREAT job. BUT … The “rule” is that if the wheels are older (yours are original?), then the real solution is to purchase new wheels. The reason is that the spokes rust to the nipples, making individual spoke adjustment all but impossible. Plus, the splines wear on the inside of the hub – and those are not repairable.
New wheels are available from Dunlop through several US distributors – Moss, for example. And, there are Dayton wheels, from Dayton Wire Wheel in Dayton, OH. The Dayton wheels use stainless spokes which will not corrode, so keeping them “in tune” should never be a problem.
Locally, you can always try a motorcycle shop as they deal with spoked rims all the time. The motorcycle shops are excellent for fitting tires to the rims, as well as balancing.
Hope this little bit helps.
SAFETY FAST!
