I've got an older Spanish 12 ga. SxS that has Eig Eibar stamped on the barrel which I know is the region is was built in. I'm trying to identify who actually made the gun and the year it was made. I took the gun apart and found a some proof marks of which I've been able to identify all but two of them. The markings that I haven't been able to identify is the letters "WC." stamped inside a diamond shape and the stamped numbers 46760. Does anyone on this group happen to have any additional info or websites that could be shared so I could find the info I need? I haven't been able to figure out how to attach a picture or I'd do that. Thanks
