What Year was this produced ?

That style would be from the mid forties to 1960, maybe a little later. Decaling wouldn't be correct.

Other than paint color that would be 50;s until ................................... Does Cat still sell a bucket pump for rollers?

The earlier Alemite bucket type pumps Cat sold had a cast handle. I don't know if the base is cast or not but heavier duty looking. There are threads on the site about the very early grease pumps. One was a bucket on 3 legs with a hand crank rather than leaver like your showing.

I am just Glad we don’t have to lug those Cat Guns around anymore! That’s something from the good old days I can do without!!!

***I second that one Mr. 17A Farmer!  I decided to lube my 1115 JD Killefer disc, along with a Goble drag disk, and my IH drag ridger, which were parked at my mothers farm in the center of town. Uggghhhh.... I thought to myself why someone did not invent a holder or such on an implement, so you would not have to lug that miserable thing around. The one I used, was the later style with the stamped handle, which I think is a little bit lighter than the cast handled one. They get lighter as you pump out the lube! LOL Glad I don't have to do this for a living anymore. JM***

Thank You for the replies.  I was simply thinking a grey Caterpillar Bucket was like same has the tractor colour change in 1931 to yellow.  Now I see your grey bucket with the Cat E Box logo.Question when was the Cat Logo E Box Used ?   My Tripod Unit Actually has the same Oil Pump Gears as my Best 30 Engine Oil Pump. Found this out after remanufacturing  New oil pump gears for back to a CLB  Blue Print from Cat Inc

Best Machine Project.I learn something new every day LOLSo what Model of Tripod Grease Pump do you Have  ?If you don’t ask a Question, How can you expect an Answer  Smile.Catman

Hah! I wanted to say that looked like real gold leaf. My sign painter puts a protective coating on it, otherwise it will wear off? No cranking on that handle! JM
