FWIW, I was selling some on the HAMB, had a bunch from an old junkyard and didn't really think anything was wrong since they were "historical documents" and expressly not for illegal purposes. Well, someone ratted me out to the state and I got a call from the treasurey dept. I was told all junkyard titles are supposed to be surrendered to the state and they ask me to send all mine in. I also asked them about a bunch of old data plates I had pried off some 40s and 50s cars that were in a dam. He said I should also destroy those and not collect them.
Now whenever someone signs up and their first or second post is looking for a title, I smell a rat. Especially when it isn't even for a specific vehicle and you don't even give any basic information about yourself like where you are from.
