I've done some research but haven't gotten a definitive answer so I thought a post here would be the right place to get help identifying the model of my Buffet Crampon clarinet. It has the golden "Buffet Crampon A Paris" stamp but no model designation like E11 or R13 or any other markings I can discover other than the serial number, 2509xx and "made in W. Germany" etched below the serial number. It is all wood, I assume grenadilla, and I've always thought it was an E11, but recently, when asked, didn't really know how to tell. I bought it used maybe 15-20 years ago.
It plays fine but is about due for a repad and I would like to have better information before I decide how to proceed. Thanks for any help you can give.
