OPINION:
I don’t know that I would want that gun back.
I wonder what kind of history it has since it was stolen.
That said, if you received a letter from the PD regarding
stolen property — that sounds like pretty standard wording
for a form letter for recovered property.
I think the best thing to do if you have questions is to contact
the police department property clerk (the number is probably on your
letter) or the recovery unit who may have sent you the letter.
If the gun is involved in some sort of an unresolved crime, then 1. Jeff Gordon would've had a visit already, and 2. LAPD wouldn't be contacting him to give it back.
This firearm is quite valuable.
