Here is another item from that horde of old auto repair shop tools I've been selling off.  This is some sort of an air powered (meant to work with your pneumatic air lines in the shop, I would guess) grease gun or pump.  Not really sure about this item, but I did unscrew the two end caps.  One end (the end with the air-line adapter on it) is clean and empty, the other end is still filled with grease.  Many photos so you can judge this item for yourself.  It is about 9 1/2 inches tall including all parts, and the item boxed to ship weighs about 2 1/2 pounds.  Look over the photos to know what the heck this is, and if you know what it is, I would love to hear from you!  Priced to sell, with only actual shipping cost charged (choose the option that works best for YOU).
