Anyone see one like this before? I am assuming it to be a Plain Jane "Black" based on no apparent color to those little nubs that Grado has, but I can't place it with the colored rectangle to any current or past cartridge models. At least after looking at a couple of sites. Any info on dating it would be good. I just got it as equipped on a Dual 1245 table I purchased
, though those never came with Grados to my knowledge.
