It was another nice day so I got a chance to take some pics of the portable pump.
The pump is an American Fire Pump Co. - Model 3XD (the pictures also have a view of an American add showing the pump).
I found the pump in TN by watching craigslist.
Here is a link to some photos. These photos show the pump in the condition it was purchased. Since I like original condition I am only planning to give the pump a good cleaning. American Fire Pump Co Portable Pump 3XD
