I'm third to vote for 3/4-ton (150). I can't see enough of the engine to tell what it is. A side view from the spark plug side would help. As Tim posted, numbers. We need numbers to really help you.
An important consideration when buying any vehicle is the title. Does it have a clear title with the correct VIN/serial number that matches the truck? Every old/antique/collector/hotrod/ratrod discussion forum has posters who bought an old ______ without a title, and now ask "what do I do?". Be smart and don't do that.

Edit: I don't intend to be harsh or critical. I like that truck. Good luck whatever you decide to do.
