Sav-A-Stamp Postal Scale
According to National Postal Museum Historian and Curator of Postal History Nancy A. Pope, "The amusingly named Sav-A-Stamp scale could weigh items up to four ounces. The attached clip held letters or small mail pieces to be weighed by the pendulum balance. The scale [shown here] bears a postage rate chart that places its manufacturing date between March 26, 1944 and September 30, 1946, when the U.S. airmail rate was eight cents per ounce."
She goes on to say, "Manufacturers in the U.S. and other nations produced letter scales for use at home. Personal letter scales were popular through the mid 20th century. They could be purchased for relatively low prices. The Sav-a-Stamp scale sold for 69-cents in the early 1940s. Businesses purchased items such as this to give to current or prospective customers."
