My vision is not what it used to be, and I have a heck of a time threading my antique sewing machines without reading glasses. So I bought a really neat set of 1850's spectacles to wear with my Civil War costuming. The side pieces have small loops at the end, so I decided to get an antique chain so that I could wear them. When I got the chain shown below, I was guessing that this was an old watch chain of some type. There is a very tiny patent number on it. It says "Pat No. 2232868", however when I look up that number, I'm getting some kind of industrial process from the 1940's. Can you guys give it a try to see if you can find it?
