Once had a really nice Winchester Model 12 in 12 gauge. Got tired of it so got a table at a gun show and put her up for sale. Had a very decent price on it and had a lot of lookers but of course money was damn tight at that time. Had one "expert collector" extremely interested in the gun at my price. Said he'd take it if he could take it apart (didn't know if he was referring to like field stripping or detail). He got it broken down without any springs hitting the ceiling or pins rolling around on the floor. After reassembling it, said that it was a great gun, just what he was looking for but didn't have the money at the moment. He walked away quickly and shortly after, another fellow asked to check it over. In closely checking it, he indicated that there was a rather important piece (forget now just what it was) missing and the gun would not function without that missing piece. I knew that the "expert" swiped the missing piece because the Model 12 had been functioning perfectly for me prior to the gun show. NEVER AGAIN!! I have had people ask if they could strip certain guns and I have always told them, "sure, right after you pay for it and if there is something wrong with it, I'll refund your money". I hate thieves and liars.
