Thanks for all the information, guys. I believe this gun must be one of the true sidelocks as it has arrows for cocking indicators on tumbler axles and ten gold roses inlaid amongst all the relief scroll. And it is a Vincenzo Bernadelli marked XII on water table which I understand means 1956 DOM. What is their top grade model called and what would it have sold for in the 1950s? Thanks, Sandlapper
