I would like to sell a vintage Singer Sewing Machine with cabinet, but I can't determine the value. The model number is G7848221. The machine appears to work (belt moves and nothing appears frozen), but I don't have a needle to determine if will actually sew. I'm not positive that the cabinet is original. The history that I am finding says this is a Redeye model number 66. The faceplate that covers the bobbin is missing. I am very willing to provide any other information. I would provide more, but am not sure what information is even needed.
