Some time ago, I inherited my grandfather's Selmer clarinet.
The bell says "BRITISH AGENT" below the customary Selmer logo and then another logo that says "SELMER LONDON" followed by a "MADE IN FRANCE" etching. The only numbers I can find on the body is "XM555" and it appears on both the upper portion and lower portion. I can't find any reference that give me a clue how old it is, what model it is or how much it might be worth.
I know that Selmer Saxophones, especially early Mk VIs like my dad's are quite valuable, but I know nothing about clarinets.
Can anybody help?
