Wow...you did a great job with the scans and comparisons! I'd seen Greg's question before, but I hadn't seen your response...

(confession time...sheepish grin) with too much time on my hands today, I started to wonder if I could take a highly detailed digital photo...by taking the photo through a jeweler's loupe!

Turns out I could . Then the linen version was too large to upload into Greg's system. I was playing with image shack...trying to remember how to use it, when I posted the tests .

For whatever it's worth...I agree that the linen version was probably the older chip, as that's the one I had a TCR # on.
