Dig, dont bother bringing any unless they are either
-Grade 2 or higher,
-A Sweet sixteen
-are in pristine condition.

There is a wide band of pricing, well used but not abused guns usually find a home for $400. I was recently offered 5 european A5's for $250 each, but I had to take all of them.

And there is usually a preference for guns with the Browning name on them. Most of the FN production you see in Europe will probably have FN marks and not have the Browning address on the barrel.
