I have a old Chatillon spring scale/hand scale that goes up to 64 oz. and 2000 GRS. I can't find anything on this scale. I have found some similar ones but not this exact one. I'm trying to find out the age of this particular scale. I have not found one with the wording like mine has. I can find no other marks on this other than the words Chatillon New York U.S.A. engraved on the front. Can anyone help me out please? Here are some pictures of the front and back. I appreciate any help you can give me. Thank you!!!
