These marks are on the bottom of a nice silver or silver plate pitcher that my mother got from a family friend. It was the wedding silver of this gentleman who was married in the late 1950s or early 60s. This is my first post and I have struggled with the photo. Sorry for the low res. I had trouble meeting the size requirements,
That silverplate mark was used by the Crescent Silverware Mfg. Co., Port Jervis, New York. Founded in 1922.
