Three fully operational pneumatic cylinders. The housings of the two cage cylinders are not in stellar shape, but the seals, shafts themselves, and other components work great.

-1" stroke, 1.5" bore, double-acting. Repairable NEMA cage cylinder.
-2.5" stroke, 1.5" bore, double-acting. Repairable NEMA cage cylinder.
-2 FOOT stroke, ~0.6" bore, double-acting. This is a long cylinder in very good shape.

$20 for all three. I'm on the stanford campus.
