I have a pair of Rebel 7s that were made for my father in the early 1960s. The case is mahogany -- each of the speakers probably weighs 60 pounds. I think it was a special order, or a gift from someone at the company (in its Hope, Arkansas location) to my father, or something. I'd like to get them refurbished / upgraded for my father for his 85th birthday. Who does this kind of work?
