Sorry I have not included photos but I have a very nicely engraved side by side with "Silvachrome" on the barrels. The barrels also have a circle with the "Silvachrome" stamping and Eibar underneath.

The gun has a scalloped reciever and cocking indicators. It seems to be high quality shotgun. I am not sure who the manufacturer is. It had been suggested once that Sarasqueta may have made it. However, I have guns that are stamped Sarasqueta.
Your help would be appreciated.

Thanks
