Pneumatic Grease Gun--Air Powered (Glendale)

Air powered (pneumatic) grease gun that uses 14 ounce cartridges.
I haven't used it in 30 years, but it worked OK when I last did.
It may still have some grease in the tube.
It's an Allied brand, which was then made in Taiwan.
I have not tried it out.
It should work, but I can't guarantee it.
It comes with an air hose but needs a zerk fitting coupler.
