I bought this a couple of weeks ago from a guy on craiglist for $40. He didn't know if it worked or not, so I figured what the heck, it will cost me 40 bucks and an hour in the car to find out.
I am busy moving house at the moment so I won't get to have a really good look at it for a few more weeks. Even if it I can't get it to work, it's a pretty thing. I'm a design engineer, so I love it when form follows function. In these days of solid state technology it rarely does any more.
It's a 99, made in 1923.
