I got this old clarinet and i need help figuring out what clarinet this it. I think is was made anywhere from 1920-1940. It was my greats aunts passed down to my grandmother then to me. On the bell it says Pan-American DIV.C.G.CONN, LTD.U.S.A. The serial number is 114551. It has a red inside of the case and the outside it brown but kinda looks like alligator skin.

Here are some other photos. A wall hanger isn't bad either, it was made not far from where I live in France, in a small town of 900 people.... that kind of history is worth more than 50 bucks....

Found this today on Facebook

I will take some more photos later. Does the age make it worth anything more than 40 bucks ?

Looking for a little feedback on this.
I was playing this particular horn to see how in tune it was. The lower register is sharp almost to the next note and the upper register is pretty close to in tune. I had pulled the barrel probably 2 mm to get it to where it is. Putting very little pressure on the reed or it will become too sharp.
I tried a few mouthpieces and obviously some played better than others. I dont know if it makes as much of a difference but I remember reading that the large bore clarinets need a more open mouthpiece. I measured the bore and it comes out to .6" as best I could with the calipers. I do not know if a 'large bore' mp would help with this or if it is just a failing due to the metal.
