I have been trying to track down a man who was said to be the buyer of the Powell stock but so far have run into brick walls. I was a Powell dealer in Long Beach in 1972 through 1974 . Parts for a Powell have been almost non existing but I will still be looking. If your band is still OK a truck brake shop that relines truck brakes may be able to re do the band. we have a shop here in Portland called Friction Supply and Ott's friction supply so you should be able to find a similar shop there in LA .
