Doesn't seem legal to sell fender tag etc

Actually kept the original VIN. Was able to get the correct paperwork. Local salvage company (not the one where I got the car) ran the vin number. The number was still valid. They went through the procedure of putting a "mechanics lien" on the car, and getting the title in their name. They then transfered the title to me.
PS: There was no issue of the car not really belonging to me. The owner of the salvage yard knows me (not well), and I did have a hand written bill of sale from the original salvage company, on their bill head.
