Vintage 97.8% Sterling Silver Signed Necklace.

This is a beautiful vintage 97.8% sterling silver 17.5” long by 3/8” wide unique link necklace, and is approximately 44 grams. It is stamped with the Markers Mark, which looks like MHA. The sterling silver content is hard to make out, so I had the silver content tested, see above picture. My father purchased this necklace for my mother approximately 50 to 60 years ago.
