Thanks for all the input. I guess we'll see how it goes next week. How much I offer depends on the shape it's in and the fixin's that go with it. If it's immaculate, I might go as high as $700 (my enthusiasm in the moment isn't easy to tame). The guy teaches marksmanship and Utah CCW, so I'd be surprised if he didn't keep it cleaned and oiled.
