Singer sewing machines are marked with a serial number. And there is a web site that tells you what, how, and where the serial numbers originate. 1871 is the earliest machine. This one is 1892. If there are no prefix numbers, it’s old. I have (own) some old ones. But this one is the oldest I recall running across. It was in an antique store in Kentucky. The car was already loaded. Alas, no room for another thing. I guess that’s good. We don’t have room in the house either. And, then there was the ½ price Victrola. That wouldn’t fit either. I guess it’s all good.
