This is a mint condition, 5 digit serial number, 1958 Selmer Mark vi Alto Saxophone. The holy grail of saxophones. It does not really get any better than this horn. Matching serial number on neck and body, 95%+ original lacquer, and best part is this horn is a player. It has a huge sound that is unmistakeable as soon as the immediate response comes out of the horn. This is a forever horn and I’m sad to see it go.
