For sale, in excellent condition is my Besson (USA) soprano cornet made by Kanstul. I can't find out much info about its history but there is a bit on this site from 2004 that says Kanstul had designed and were making Besson sops, so this may date from arround then. Design-wise it looks very similar to the current Kanstul 1536 except it has normal water-keys and only a saddle on the 1st slide rather than a trigger. There's a ring on teh 3rd slide. Plays well, but as I'm a Bb player who am I to judge! You're welcome to come and have a blow, I'm located in Suffolk, could also get it to Reading at a push. Comes complete with besson case but no mouthpiece. Pictures on request. Looking for in the region of £500 but open to offers.
