A long story made short is this:
I received my Great-Granddad's Mark V from my cousin recently. It had been passed around the family over the years, but we recently bought our first home (Yay!) and I had lots of projects planned and no more than a compound miter saw. Before going to pick it up I was told it "needed some TLC, going over, etc." BOY, was that an understatement!
Sadly, nearly everything on this machine is broken. The work table's leading edge is rounded over, the carriage has been welded back together at some point. There is no handle to raise and lower the work table, but that's ok because the teeth are broken anyway. The table's insert is welded as well. The belt is shot as is the quadrant assembly. The speed control handle's teeth are missing. The only component connector piece is broken (sort of). A bent bolt is in place of almost every handle. That's to say nothing of the sawdust/grease/rust caked everywhere.
Luckily though, not everything is broken! Most of it is missing instead.
No miter gauge, no drill chuck, no saw arbors... But the best part is it came with the model 610 jig saw. Apparently it was leaking at some point and rather than order or make a gasket they instead replaced the 10 weight oil with red grease 
Cause you know, those are practically the same thing *sigh*Anyways, rather than try to put all my money into this machine, I have purchased another from craigslist and will likely put this outside with a tarp over it and just use it for lathe work or something... Hmmmm, maybe I made a short story long. Whoops
All of this is a preface to ask you guys if you can ID a part from a CL picture... I have an idea of what it is, but don't want to color any one's thoughts.
This is the machine I bought

What is the thing on the right in the 6th picture over? Yeah, yeah, I'll find out in a week or so when he brings it here, but I'm impatient! And, wanted to kind of introduce myself with my story.
Thanks
5200 rpm max!
