Hi JazzGoddess!. I've readed many times the same comments about after 50's Conns.I've tryed a lot of Conns from New Wonders to Naked Ladys (New Wonder, New Wonder II, Chu Berry, Transitional, 10M, 20M...) and even between two models in same serie with a very close serial number i've founded differences.I've tryed two 60's Naked Ladys with a very close serial number, one was an absolutely piece of junk and other was a monster horn, an incredible sound and playability. Just try it and try to try different horns of the same serie. Good Luck. Joe
