All things work amazing on this! I play tested it and I sounded ok (I'm a sax player...so... :). The slide is absolutely perfect. The tuning slide is also lubed up (did it with Schilke Slide Grease...TMI?....)The water key is in great working order.The bell is a gold brass color and the slide is nickel. Apparently Jazzers love that?Bell measures 7 3/8 inches. The serial number is in the 150,000's, which I Think puts it in the 1950's. The case has normal visual wear and functions like it should. This is an AS IS auction, but I have no qualms saying that this thing is in perfect playing condition!!
