Good to compare notes on what a proper/improper KM73 should look like.
These were the exact symptoms of the "bad" plates - an emerald colour
with the mylar stuck to the surface (and cracking as it was removed).

Fresh plates tend to be the artichoke, light green color. I have seen
them where they're a more emerald color too, which indicates to me
they've probably been around a while. I've also gotten them where the
mylar was actually stuck so hard to the plate that it's torn. Box Car
recommended under those circumstances to remove the mylar with a
little heat from a hairdrier....which worked like a charm.
