Iirc Kaman were kinda caretaker owners, continuing the previous work, not changing things up.
I wish I could find a $70 tolex 1518 taking up space at the Salvation Army store. I'd give it a good home too!
Oh, and thanks for the info bit there on Kaman!
True enough this stuff is floating around here. I remember being at Berklee for a year in Boston, and the Series 6 models were appearing in the hands of a privileged few hot-shots. There does seem to be a cache of these old boogers left by those who moved on, somehow... I'm homing in on a Series 6 as we speak. Hey, I might need a back-up!
I'll keep an eye out for you if you're looking...

From a sound engineering perspective it's a fool's errand but I'd still like to hear / feel it up close and personal
