Vintage Cufflinks Signed WC 1812 Military Screw Back Set of 2

Preowned, Vintage, Set of 2, gold tone Military Cufflinks. Please see pictures and video to aid in description and for signs of age and wear. Some discoloration marks on underside of gold tone pieces and a mark on one silver colored back as shown in pic #6, but really in great vintage condition. Fronts look amazing and have 2 different gold tone finishes. The raised detail has a shiny gold tone finish and the background is more of a matte finish. When I think about my family history and where these came from, I am pretty sure they are from the early to mid 1970’s, but I am not certain.
