As of November I've owned a visibly older Selmer Bundy alto clarinet that I got for $550 dollars being sold by a Sam Ash store in Miami. With it came a mouthpiece produced from around 1935-1956 or so, and it's serial number is 26962. I've been trying to find out how old it is, but according to the only list I've been able to find, that would mean it were from around 1917.

• There is a serial number on the body: 584168. The ligature has FRANCE inscribed on it. On the barrel, there is an appearance of what used to be a BUNDY logo, but it has disappeared other than a slight reminiscence of it.

Thus, I'd imagine I'm not looking at a proper list for alto clarinets because while the instrument seems worn, it really doesn't look like it's 100 years old, and seems to be made of either hardened rubber or plastic. Anyone have any advice or resources regarding this kind of thing?.

There is a serial number on the body: 584168. The ligature has. I've done my research and I know the history of the Bundy company, (acquired by Selmer, some clarinets are resonite plastic, etc.). I have an older bundy clarinet and the year it was made was the year they were using the case that I have.
