Way back when Bridgeport mounted a coolant pump in the hole behind the door. I have only seen 1 with a pump in all my 50+ years of rebuilding.
Paul is correct about when Textron bought Bridgeport the removed the door and thinned out the casting and there is no depression in the base under the knee. Those Textron machines always sell for less at used machine dealers. They are also weigh a lot less. I tell folks not to buy them uness you only doing light work.
