I found this on ebay just now. They look like teardrop lugs, except they fasten with screws. my teardrop lugs have studs. These are screw on. I saw an acrilic kit today on another thread here today, it had teardrop lugs and was japanese. The lugs were screwed on like most other drums. I restored my early 60's sonor kit very recently. Were sonor teardrops ever "screwed" on. Mine had "studs" and "nuts" as fasteners.
This guy sounds sorta like the scammer i read about.
