You've got a Bridgeport J head milling machine. Yours was made in 1965. I recommend that you check out H&W Machine Repair on the web, and look for the book "A Guide to Renovating the Series 1, J head Bridgeport Milling Machine". This book will tell you everything that you would ever want to know about repairing and maintaining your mill.
Please note that the J head mill has the stepped pulley drive, (like yours), and the 2J head has the variable head drive. Hardinge bought out Bridgeport back in 2003. If you go to the Hardinge website, you can download the operations manuals for free. The manuals for the Bridgeport mill can also be found at multiple sites on the web, also for free.
Bridgeport mills were not designed to be lubricated with grease. Those fittings that look like zerk fittings are actually Alemite fittings, and are designed to be used with oil. The Bridgeport mill has a constant loss oil lubrication system, so if there's oil on the foot at the base of the pedestal, that's normal and correct.
There is a ton of stuff waiting for you to learn about this milling machine. The more you find out about it, the more your going to realize how versatile it is. Once you have it running, you'll be able to make practically anything that you want. Two websites that can help you get information are Practical Machinist, and Weapons Guild. Best of luck with your new mill.
