Thanks KO I didn't know that. I saw metal hoops and automatically assumed they were MIJ add-ons. Great price for that kit.John
It's definitely possible (even probable perhaps) that those hoops were made in Japan, but those are what Gretsch put on their bass drums for at least part of the 1970's. But they are missing their inlays.
I'm glad I'm broke right now or I'd be strongly thinking about these, or at the very least the matching concert toms he has on ebay to use with my Burgundy Ludwigs.
Looking at everything he has for sale (on ebay) it looks like this was one big double bass kit with dual floor toms and auxiliary concert toms that he has split asunder into smaller, more saleable parts.
