Designed by Fenwick and Sailors a manufacturing jeweler operating in the Los Angeles, CA. area during the 1950s and 1960s... these Sterling Cufflinks are Marked as "Embossed Lion" and "STERLING"on the reverse. The patent number on the swivel locking backs correlates to 1950. The VERY Regal Lion depicted reminds me of those found on European Heraldic Shields.
SQUARE Cufflinks WEIGH ~ 16.5 Grams (Over 1/2 Troy Oz), are 3 Dimensional, Slightly Curved & have a scalloped edge. Faces MEASURE a Tad Over 3/4 Inches... Mid Century cuff links are in VERY NICE CONDITION! Have not been polished in many years & appear to have a lacquer finish to help retard tarnish.
Would make a GREAT Gift for your Favorite Aristocrat (ha ha) or addition to your Vintage Cufflink Collection!
