Probably from PD's who make an order, then don't use them and then sell off either the uppers or the whole gun to dealers. It's weird what some PD's do with their stuff.
In the small town I spent most of my childhood in, they had several brand new in box tommy guns from the 20's or 30's that were in the registry even. In the late 80's, they sold off one or two of them and outfitted the departments new tactical team with all new HK goodies including at least one PSG1 (if I remember correctly).
My parents were both LE at the time and I got to go play with the toys when I was a kid. I was an HK fan back then as well so it' was like walking into my own private version of heaven when Ed (the head of the tac-team) let me in the armory for the first time.
