Wanted to sell it but no one here wants it. If you look at the plate on your machine there is a number and some letters I think, if you call Singer they will give you the exact date and where it was made. Hubby made a great find.
I did look up the serial number - the number was released in December of 1919, one of 50,000. However, I can't assume it was actually made in December of 1919, more likely it was sometime in 1920. The motor and belt look new, so it may be a very recent conversion.
It's more difficult to sell a machine online, probably because of the weight of these machines. They are HEAVY, and often damaged in shipping if not packed properly. If I had known that you had one to sell, I would have definitely been interested, but now I have one. I consider it a keeper.
