This silver clarinet was manufactured by Cavalier in Elkhart, Indiana. Serial number 49727. It could certainly use a good cleaning but I'm not sure what to use that will not damage the finish. Comes with mouthpiece and the all important and difficult to find mouthpiece barrel. Hard shell case with red velvet interior and marching band music holder that screws into the top. I don't play clarinet myself so not much info on how well it plays. All the keys seem to be functioning properly but I'm sure a little TLC would bring out the best in this vintage instrument. A great addition for the clarinet enthusiast or the vintage instrument collector.
