Hello. This is a long spoon with three marks on the reverse side: CD in a square (there's also some sort of shape between the two letters that I can't make out), the number 61 in a square, and DURAND in a rectangle. I know there was a Cyrus Durand who worked in NJ for a very short period of time in the early 19th century, but the mark I've found for him is "Durand" in cursive. Any assistance is greatly appreciated! Thanks!
