I own an 1876 SAA as shown. Ever so often I enjoy taking out of my safe and handling it. Today, for the first time, I noticed some etchings or whatever on the left side as shown. Obviously, they are very faint, so much so that I really only saw them with a printer's loupe. I have done my best to photograph them. Attached is my best effort to show. Has anyone come across similar marks? Would love to know what they indicate. Thanks for looking...Dan
