found my old sax and wondered what year it was and if it is rare or common. The sax was purchased in the early 70's from a professional sax player. On the back side towards the bottom I think is the Registration number 25534. On the front side of the horn is stamped:
BRITISH (cant make out next two letters) PPE
the finger pads for the keys are inlaid with what looks like "Mother of Pearl" but pretty sure its not.
