Three cylinders -all will full stroke with 40psi air in both directions-$75 each plus mail. Two pump motors. Blue one is 6 volt, the black one is 12 volt. Both run OK in both directions. $75 each plus shipping. The green controller and pump motor are OK, that is, the 6 volt motor runs. Controller condition is unknown. Same for the red setup except that 6 volt motor doesn't run, bad bearing. $100 for the green and $50 for the red. Both are plus shipping. All of the above prices are guesses...am open to offers, but would rather junk than give away. (715) 442 9023
