Cessna hydraulic gear pump new old stock commercial grade never run

Description

Cessna hydraulic gear pump new old stock commercial grade never run.Its looks like the drive and has rust but its the old preservative I cleaned it off with a brush on the tip of the drive end see photo. I don't know the age of these. I used them to drive landing gear in simulators and never had a problem. I ran them at 1500 PSI not sure if they are 3,000 PSI or not. Pump rotates freely by hand. They have a #6 inlet jIC fitting and a #4 JIC outlet fitting. You can remove them and the pump body is 1/4: NPT. I have six of these but am selling individually.
