That's quite the find!
Driving down a dirt Rd in day with my BIL I though I saw something off out of the corner of my eye, so I backed up with the car as close to it on my side as I could so if it was what I thought it was I could grab it first, my BIL has great eyes and would have been out the door and on it before I put it in park. Sure enough, there sat a cheap 12ga pump. I'd never take something like that now, I know where there's a nice set of logging tongs I could grab close to the Rd right now(been buried in snow all winter) I won't get, but if I found a gun in a cluster of trees like you did I'd be all over it, very cool stuff.
Any pictures.
