I just obtained a bunch of sealed tapes, "Auduiotape Q19 by Capitol. High Quality/ Low Noise. Cushion-Aire w. Backcoating 1.0 mil polyester. I've never seen this one before, and have 15 or so each of 5" and 7" sealed boxes of it I'd like to describe in an Ebay listing. Is this a repackaging of an Audiotape product with a different product number? Baffled (also known as Steve Smolian)
