Merry Christmas To Me!

While researching some funky antique machine feet a few weeks ago, I found myself on eBay drooling over a 22-piece set of industrial feet.  Hell I don't even know what half of them do, but for $20 I'll enjoy figuring it out!  Some of them are duplicates of feet I already had, some seem useful...and the rest will just look pretty hanging out in my workshop.  The magnetic seam guide seems pretty nifty (am I the last to know about these?)
