A rare A.Y.A Countryman side plated side by side, which would have been a considerable sum when new, and this one is still in pretty good nick...
 
12 gauge, ejector, double trigger, 2 3/4" chambered and choked 1/2 and 1/4 with 28" barrels.
 
A high quality, traditional side plated side by side that could be yours for £599
