Question:

How can I find out the value of a Artley Clarinet 80S, and the clarinet was made in either 1875 or 1876?

comes in a case and theres a number on it of 155397 I'm not sure if that is the model number or what, but I would like to know the value of the clarinet......it's in great condition

Best Answer - Chosen by Asker: I'd suggest you search around for musical instrument collectors and see if one will do the research for you. Since we're good at finding dead people, that probably won't be very helpful to you (unless you've got the name of the first owner and want someone to find her). You probably need a living person who has the knowledge and resources to help you. I can definitely imagine there are collector groups out there who would be more than happy to help you research the piece.
