I have a Kanstul 610 and had a couple of questions regarding this 'student' horn that hopefully a Kanstul employee can anwser. This horn isnt listed anywhere on your site or are there any other references to it on the net except at Pick music (who I bought it from). It's almost as if I own some kind of phantom horn I read the article on Mr. Kanstul and noticed how it referenced the building of the Besson 609 (I presume 609 it just said student models) and how it was used to train the younger employees but now y'all decided not to produce any more. Is my 610 one of the left over 609's that has a different receiver and silverplated? Or is it a horn you still produce. How many of these 610's are out there? I really think someone at the Kanstul factory screwed up big time because to most at the atlanta fest, that 610 outperformed the 700 and the 900! Of course I'm not complaining because I got it at a good price and love how it plays. I guess I'm just curious if I'm the only one out here with a 610 :?
