Don, after seeing your comparision pics, I am now wondering what I have. Here is a pic of my posi label. I bought this back in the 80s. It is a peel-off adhesive type with Brown-Bridge strip-tac words on the back. This is the one I scanned and was going to try to copy, but the background is off white and needs to be cleaned up.
The A and the C look to me as a perfect match for the originals.
