Used nitrogen regulator in good shape. The clear lens is missing from the tank pressure gauge, but it still works. Made by North American Dispensing Systems (NADS, lol) which was bought out by Taprite. Note it has the unique connection for nitrogen. It can also be used for CO2 or beer gas blends, but the regulator has a different end to it.
