I'm thinking those were an entry level line of cymbals made of brass.... maybe 1990s into the early 2000s? Replaced by the SBr line? Maybe? Dunno. I've seen them with used starter kits, but never played them.
I sold the torque kit vintage drums. They are about 20 years from when I got them, to where they are now! Not sure how old they were to the original owner but anyway I bought a breakbeats kit by Ludwig
