Does anyone know where I could get a manual and/or date of this Free-Westinghouse sewing machine? It was given to me by a cabin neighbor and she said she used it to make curtains in the 50s. That was the last time it was tuned up. I found one for sale on eBay but didn't get any reply from the seller. Any help is appreciated. I don't know how to use it and would love to see if it works after oiling.
