I was at a tactical gun shop today. I seen they had a sxs in the rack. It was a box lock with a hinge pin. The only markings on the side was F II X. There was some engraving that went around the receiver and on the toplever. It had Philadelphia Arms Co. on the rib. Any quesses on what the grade of this would be. It was in nice shape. I think the serial # was in the 13000 range and it was a 12 gauge.

Thanks, Larry
