Selmer Mark VI Alto Sax

I have a 1971 Selmer Mark Vi Alto sax for sale.  It is serial number 190***.  Amazing low register that is extremely easy to play. It has nearly perfect laquer, with really just a few scratches on some of the keys and on one of the rods on the top hand. You also have the option if you want it shipped in the original selmer case(which is very worn, with the springs on the latches not always working) that is heavy and protective, but has a built in place for a flute AND a clarinet/oboe, OR a relatively new protec case that fits the horn perfectly, but doesn’t have the extra space or the feel that you get with the Original Selmer case.
