David,
“I have in my drawer, probably fifty squeeze seals that will print a seal ring without the certificate data if you squeeze properly. I don’t think any of that proves anything.”
Does the location of the seal in Red Steel’s filtered copy shed any light on this? On all the legal records I have with seals, they are much closer to the margin—else you’d need a seal with an implausibly large handle. If any of your squeeze seals is capable of placing the seal at that approximate location, this would rule out the theory. Admittedly, having zero of 50 seals not be able to come even within 2” of placing a seal that far from the edges doesn’t prove anything definitive, but would cast further doubt on its authenticity.
Matter of fact, seals are readily available with longer reaches--I have one of those I know about and I know I have seen many others.
