Hi Mike,
I didn't notice your reply until today. I know, I should spend more time on my own board. It gets to where I just run out of time for the things I enjoy sometimes.
Anyway, I'm glad you bought the gas gun. I was in there again about a week later, and noticed it was gone. I told them when I took the photo that I was going to post it on the board.
So, the reason I think it came from Baton Rouge is that they told me they had just bought a bunch of items from the Baton Rouge Police Department, one of which I purchased, which is a 1982 vintage Smith and Wesson Model 686 pistol with a 4" barrel. It is marked "BRPD" under the cylinder. Please see the photo below. The case had about 6 gas guns, only one of which was a Fed Labs, which you bought. It was the first time I'd ever seen gas guns at AIM Surplus. The other gas guns were two different models of later styles, circa the 1980's. So while the guy I spoke to did not say that your gas gun came from the BRPD, he implied it when I examined it, and the 686 that I bought. I told him I already had 2 of the Fed Labs gas guns, but that theirs was an early one that might get collector interest. I think it came from Baton Rouge with my pistol.
