Thanks JLLebbert.
The strip does not have a plate #; I shouldn't have called it a plate no. coil, and even worse, I should have checked the
ebay listing more carefully before buying; it was sold as a strip of 5, not a PNC5; I didn't notice, so I guess I wasted a couple of bucks.
When I do acquire a PNC5, I now realize that the "V" in the plate # will confirm the ID (assuming Scott doesn't have the plate # listings attributed to the wrong stamp!

) I have a 2904A pair (with a V in the plate #) and a 2904 PNC5. The outlining in 2904A is visible only against the light background areas but even so, is easily distinguished from the non-outlined 2904.
I was more curious to know if anyone agreed that the 2011 catalog note on text outlining is reversed between 2904A and 2904B, while the die cut gauge info is attributed correctly to each stamp. Whichever info is wrong, did Scott correct it in later catalogs?
