Devil Satan Sterling Silver Cufflinks stamped . PAT. 2472358.Tested w/ 18k acid.

This very unique cufflinks are perfect for your collection. I looked all over the internet I can’t find any similar to this. The lady I got this her father was the first owner. They look like they are two different material in the back but on the front they are the same. They both tested for sterling with 18k acid. I tested them few times just to be sure. The Pat number also marked in a different directions. This makes me thinking that probably he had 2 sets or maybe they were bought like that long time ago. Please see pictures and let me know if you have any other questions.
