Sure, these were a short lived 75hz lead cone (5-6 years, done by 96) that was an attempt to get back to the "pre - rola" era tone. It was discontinued about 14 years ago.
I have about 8 of them myself in both G12H30's and G12M's. Much nicer than the current models, IMO, and a couple notches below pre rolas and mine, but still worth having if you can find them.
