I have my fathers sax and he is askig me to sell it for him. He has been playing reed instruments his whole life, now 82. Unfortunately, he is unable to play anymore which is heartbreaking for the family, knowning how much he loved to play his instruments. I am writing you guys for some help. I really don't how to post this for him with all the proper information. I know it's serial number which I was able to find the year of manufactured. What I don't understand would this 1956 Mark VI Sax be considered "Super Action" too? Thanks for any help in advance!
