I believe that the OP's machine is more than "just a drill press" . It is incorporated into what I believe is a head machine for doing valve guides.
I was thinking the same thing.

The fixturing is for holding a head for internal combustion engines and then reaming out the valve guides or boring for valve seat inserts. Specialized equipment for the engine rebuilding tradesmen.The table fixture is interesting.
-That is a match for what the OP has, good search skills on that one Larry. You've caused me to go searching for better information. It appears to be part of a machine offered by Winona (Winona-Van Norman) that has an Arboga drill press with an air table mounted to it. I've not been in the automotive end of shop work but all the videos of good automotive machine shops used a milling machine or a jig borer for valve seats and especially for valve guides.I believe that the OP's machine is more than "just a drill press" .

Never knew air bearings were ever used on machine tools of that era.By the way, the table rides on a bed of air (pneumatic) which I understand was not a standard feature.
