Well it's nice to know it's rare. It's odd just how many rare things show up on our side of the world. I bought it from a guy selling a beat up Maxtone kit and these hats were sitting loose, propped against the FT in one of the photos.
It's amazing what can be found grouped around some lower level kits.
My best Craigslist find so far was a less than $100 Star 3-piece surrounded by a mint 70's Super-Sensitive, Porto Seat throne, Spur-Lok hat stand, and a Zildjian early sixties cymbal line-up of 22, 16 and 14 inch hats in great condition.
Kinda embarrassed about how little I paid for the whole package......ahem
Congrats on your hats !
