Gun has a new air valve and tubing. On the first picture the knob on the cup lid is missing, the bridge moves freely when the lid lock is disengaged. There were two knobs on the lid that lock the bridge in place, one is missing. When locking the lid you have to make sure the lid is tight against the remaining knob.
Multi-position pick -up tube(creates longer use without refill). Optional air inlets(provides non-bleed to bleed conversion). Maxum II two stage trigger(air and paint) on a two pin trigger. #3 needle set in gun.
We have been using Titan Capspray guns and turbines for 26+ years and are experts in refurbishing and restoring them back to their original excellent working condition.
