In the cabinet of my grandmother's ancient Singer, I found an attachment for the machine which had been mailed to her from Chicago, Ill., to Yakima, Wa. It was mailed in a small manila envelope, and the postmark is unreadable, except for the postage meter "stamp" which says 3 cents. The instructions inside have no copyright notation. My question is how would I ascertain what year this was mailed to her?
