I don't know that this qualifies as a fantastic find, as I grew up with this machine. It sat broken in my dad's shop for as far back as I can remember. I had it restored in 2000, and recently decided to fire it up and make a video of the machine in action. You can see the video at my blog. While trying to find more information about the machine online, I happened across the patent application from 1935, and that is also posted at the blog.
