Tippmann SMG-60 Internal line valve, in great shape but untested, see photos. Came with parts from Gramps and Grizzly. I have not tested these but assume interior seals are bad from sitting. Not sure if these were removed from a paintgun or were NOS parts. They were with other NOS parts but also used parts. See photos. Likely from 1987/88 so have been sittin 30 years. Some wear on allen screw lock down cavity. See photos. Some have steel ridge not pushed all the way on. Several available. One included.
