Hi all,
the day-job has just listed a pair of air-over-oil press cylinders, sometimes called pneumohydraulic cylinders.
I have used this type of cylinder for print machinery that i built in the job and they are very useful, thought this may be of interest as rivet squeezers, small part punch presses, etc

They are in excellent condition
