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.
-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.
-A machine by Serdi seems to be preferred, the Winona models are less expensive but not very well thought of on some speed shop websites due to lack of rigidity by design. I watched a few videos of setup and operation of a Winona model, seemed a bit marginal to me.

@GaryShop26 : For further pricing information or a shop manual you'll have to identify which Winona model it is, a Winona PH-2000 seemed the most commonly available. If you're selling, it would be quite important to ensure the air table works freely and the drill press works as it should with no abnormal noises. A similar model is in the link below.
