Does the 1906 Conn have the union label stamp? With a union lable stamp, since this saxophone was made before the sale of Conn to Carl Dimond Greenleaf, it would be quite valuable to a collector. It's worth more as a collector's piece rather than a playable saxophone. This is not a horn that you would want to play, obviously. It would be worth more if it were all original. It shouldn't be lacquered. It should either be nickel or silver plated, or possibly bare brass. Without seeing it, I can only tell you that if it is original and in good condition (no dings or dents) it's worth $1000-$1200. If it has been lacquered, or has any damage or additional markings (where someone engraved their name, etc.) it would be worth considerably less ($50-$500) As for the neck, I would suggest offering it on ebay, starting the bid at $50 and go from there. I'm sure there are a few people looking for a microtuner neck for a Chu or a New Wonder Series I. I saw a Microtuner neck for a 6M (underslung) sell for $276.00
