I wonder if someone can tell me the origin of these spoons. They appear to be very early American, but I can find no identification for the “reverse Z” mark, nor do I understand the number “4” also on the back. By appearance these are very early US. Just 5" long. Very light weight at about 7 grams. There are five of them. Purchased here in Vermont 30 or so years ago and still sitting in the “mystery box”. Any help greatly appreciated.
