I would like to find out what year my sewing machine is and how much it can sell for. The serial # on the plate is FR3323373

Look at this and see if you can find out more: ISMACS - Vintage, antique, and rare Sewing Machines
This is the International Sewing Machine Collectors' Society
If not, do a search on the Internet. I do know that it was made before 1920, though. You will find some interesting material on your machine at: Article on the White Sewing Machine Company
