I'd take the above suggestion of ID'ing each part. At least by stroke and diameter. Then just post things on EBay and go from there. If you're looking for faster results, you might see if you have a local electronics/mechanical surplus store in your area. They might buy the lot off of you for a bulk price and then individually sell the cylinders off themselves. You won't get as much money, but you'll get it faster with less hassle.

To the other CDers who might respond, note our OP only has these two posts on CD, so he's probably not with a FIRST team. As such, posting the parts for sale/trade here on CD probably isn't going to get him the results he's after.
