Hey Mike, where did you find that thing? I've got the little brother to it, I found it a few years ago at a hot rod parts swap meet, either in CP or Valpo. My plan was to use it for drilling holes for pins, but mine is missing the auto advance too, along with a couple other parts.
This little one might look good on your wall next to yours. Sort of a 'non-working antiques' display. I'm trying my best to avoid getting put into such a display myself, but some days I really feel like I do belong there!
