OK, the “ground off serial number” story was from the gun shop guy who posted that he sold the weapon and was interviewed by ATF. Since the rest of his story checked out, I give the remainder of his story higher credibility, although I am still going to wait for official confirmation.
But given they had the receipt, it wouldn’t have mattered if the numbers were wiped, the receipt would lead them to the gun shop and others have said that the numbers can still be read if filed off.
Oh yeah, the receipt. Duhhhh. Sorry, I’m not awake yet. :)
