That reminds me of something that happened to me when I got my 931. I took it apart to clean the internals. When opening the case one of the screw holes where jammed up with ****, I figured spiders,bugs, paper or leaves, cause I've seen that before but I pulled out a big fat joint
It looked like they lit the end put it out and stashed it in the hole , the previouse owner was probably about to get busted!
And no I didnt smoke it, That was probably some weed from the 80's, it was dried up and as hard as a petrified turd.
Nice score by the way. I had a chance at a mint 935 for sale but dude wanted $300 and would not budge on the price.
