Product Name: 1922 Antique order Singer Sewing Machine In Case Working
1922 Antique Singer Sewing Machine In Case Working. Picked this up in a local estate auction. Very cool heavy sewing machine I looked up the serial number and it says it was made in May 1922. Don't really know how to test all the features but plugged it in the light came on and when I press on the pedal the needle goes up and down. That is my extent of testing it. The case does and machine do show some signs of wear but it's 100 years old what do order you expect.
