I have just inherited these antique musical instruments. I know nothing about musical instruments. I think they are clarinets. They are marked Adler Bamberg. I think they date back to the early or mid 1800s. I have tried to research them but have only come across the link below for a similar item. Can anybody tell me anything about them. I am not even sure how to handle them or what to do with them. Any suggestions would be greatly appreciated.
