This is a beautiful original matte silver plated C.G. Conn 10M tenor saxophone, serial number 310618.
This tenor is gorgeous, with over 99% original silver finish remaining, and it plays with a HUGE sound. Silver plated 10M's are fairly rare, but were made throughout the run, this one was manufacturered in 1945 and features rolled tone-holes. The horns looks incredible. The only real wear of note is found on the thumb rest, as seen in the pictures. Otherwise the sax is close to perfection. There are no dents or dings anywhere in the horn. The neck is in great shape as well. All of the rolled tone holes are in perfect condition - they have never been filed down.
This tenor is a phenomenal player. Nice spread sound, very open resonant feel. The response is lightning fast with no resistance. They don't get better than this!
