Default Altec Digger Derrick question

I got a very old, 1971 I believe, Altec Digger derrick, it no longer has the digger on it but I am just wanting to use it as a crane to set things up and move heavy items. When I got it, the original pump had been removed from the hydraulic system. I have it here inside and can plug it into shop hydraulics and make the basic functions and winch work fine so I feel pretty good about it. However, I am no hydraulics man and am trying to size a pump for this unit. I would like to make a skid and use a car engine, or other power source to run the hydraulic pump and have the tank and unit all mounted on the skid so I could use it for other applications around the farm. I am sure when it was equipped with the digger that would have required a lot more capacity than just rotate, extend and winch but I have no idea what size of pump to get?

I have a pump that was taken off a working trash truck that is very large, it is probably overkill but I have thought about using it. It has no tag to identify it but it is blue and has a large G in the casting. I have seen the G before but my online search has not found anything. If I knew what it was I could size it in horsepower better to an engine.

If anyone could help or make suggestions, I would really appreciate it.
