That is really neat. I was wondering what company sold The Elgin, as Free made machines under that "badge" for quite a while. Now you'll need to get an Elgin Rotary and a Free Rotary so you can have two matched sets LOL!!
They seem to enjoy being in rather large "herds" - at least that is my excuse. Like strays, once a few find a good home at your place, they send out the message and pretty soon machines just seem to pop up no matter where you are, or if you are looking or not.
