Wanted: Sold at Oxford gun show

Winchester model 88

Looking to track down my father's rifle. He had to pawn it last year when he got hard up and the individual that ended up with it sold it from under him. I would love to buy this gun back or at the very least know where it is. I've got an 88 of my own here (in twice the shape the rifle in question is) I would straight trade also. Any help is appreciated thanks in advance.

The rifle I'm looking for is the one on the right in the pic. Finish was worn off the stock in many spots and had a 3-9x50 scope on it with a gold ring and a leather sling.
