Anyone have thoughts about what this would do to the value of a 1949 Zephyr alto? I'm looking at one and the seller states that he had it delacquered and the brass polished becase this was an original finish offered by King. Not sure this is the case though for 1949. Seems right in the sweet spot for these horns and I've wanted one for a while, just concerned about the effect on resale. Thanks!
