I just purchase a new Kanstul 1600 from my local dealer. I notice that the instrument shown on the Kanstul web site has the initials WB on the mouthpiece receiver. My instrument has the number 1600. Has Wayne and Kanstul parted company and is that why my trumpet has 1600 instead of WB? I've heard Wayne is going with Yamaha. Is my 1600 still a WB without the initials?
