jbtsax, the only possible connection between the 2 brands could be, and I stress could be, that when B&S ceased its production of pro horns in Germany, they were planning on continuing to make some kind of pro model horn in Asia. Since JK has their student horns come from where Taiwan(?), it is I suppose possible that B&S's student model horns & any pro models that they might now be making, could be coming from the same factory.
This is pure speculation on my part, but if there is a connection between the 2 companies, it would have to of course be a new one, and that would be the only one plausible explanation I could come up with off the top of my head.
