Thanks guys. I'm working on getting pictures linked of the cylinders, pump, and valves. I cleaned them up a bit last night and have some information on them. My memory was not quite accurate on the size, but these are still BIG cylinders for a 1 ton.
Cylinders - Extend to 65" (forgot to get unextended length). One has the number 266 stamped on the bottoms cylinder and both have 594 stamped on the stamped on the big cylinder seal and 593 stamped on the middle cylinder seal. The large cylinder is 4" OD, middle ram is 3 1/2" OD, top ram is 3" OD. Assuming a 2000 psi pressure, I'm looking at about 10 ton per cylinder. MUCH more than my little tonner will handle (3 ton max'ish).
Pump - Gresen Minneapolis Model "TB" cast into the unit, 12C is stamped under the model information. Serial number F3 is stamped. It looks like an aluminum body. The unit looks in good shape.
Valve - Gre-Sen Minneapolis 300 cast into the unit. E2 stamped on it. 3 13 2 cast into it (like a date stamped casting mark). The unit looks in good shape.
