Is there a website or book that I can look at getting to find out how old my Holton is and what may be the Blue book price on it if I decide t sell it? I know that I've had it for 34 years and there was on other owner that had it I think for 20+ or so years. Just wondering? Thanks for any replies I can get on this.

http://www.missouri.edu/~cceric/sn/holton.html might help you with age. As to price you may find http://www.horncups.com or http://www.hornplayer.net useful but I'd favour contacting a good horn dealer for their opinion
