This is a very nice pair of vintage cufflinks, and see second picture, for the "Swank" hallmark (both are so marked). I find no other hallmarks on them, and, since there is a bit of base metal showing on one, I am going to say they are silverplated. All in all, they are a handsome pair, some wear and tear, but, the gentlemen whose estate they came from (I personally knew the man) took kind care of them.
The links each have double overlapping "O"'s. Each "O" is 13 MM across; in the overlapping formation, across, each is 21 MM. The shank is 12 MM and the crossbar is 18 MM. The hardware is very tight and secure on both.
