Chris, I couldn't agree with you more! Fake paperwork is exactly the same thing as fake cowl tags! (or are the repro cowl tags just "for display purposes only"?)
If he's smart enough to create them, then he's smart enough to know he's selling them to people to commit fraud. Now, I'm no lawyer, but if one sells something that is used to commit fraud, I wonder how a court would view that seller when the poop hits the propeller over a fraudlent sale involving many dollars?
Long ago, when repro cowl tags first showed up on the scene, many people simply viewed them as a "restoration part". Now, we're supposed to believe the smoke and mirrors that original appearing documents are also just another part of a restoration????? HELL NO!!!!!!!!!!
Those papers are the birth certificates of the cars we love. They may have survived, or they may not have. Either way, we only have what we have. Recreating new ones to our desire is unethical, and should be illegal.
A person may have been born with with a given name that he doesn't appreciate, so he changes his birth certificate to read Richard Wadsworth, when in reality he was still born a Dick Wad.
