If you post the part number I am sure an IRI team will be able to help you. Bimba: The part number should be etched on the size of the cylinder. The number refers to the cylinder bore, stroke, action type, & mounting system.

For example:

M-1224.5-DP
->
Magnetic Piston - 1.25 inch bore, 24.5 inch stroke - Double Action, Rear Pivot mount

Play around with bimba's model generator to get a feel for their naming system.
