Please stop by the main lobby at Munster Town Hall to see our Singer Featherweight 221 display: "The Singer Featherweight...1933 to 1961...Still Sewing Today!" The Featherweight on the bottom left side of the bottom shelf is dated 1938. The Featherweight on the bottom right side is dated 1957. Can you find one very obvious design difference? (You will probably need to see the display in person to find the answer.)
