the American Design patent with number D188,151 was made on March 12 1959. It was granted June 7 1960. The leaflet of this postal scale presents directions for use and also a simplified postal rates survey with the date January 1 1964. This was not a date on which an official change of postal rates was made in the USA. It's remarkable to see this box has a sticker of a Scottish shop. Apparently this letter scale was sold outside the United States as well. The scale has a metal shifting poise. With this, the scale can be adjusted per half an ounce. The maximum of the range is 2 ounces. Below some more pictures of this combined letter scale, letter opener and magnifier.
