This gear box from Pacific Gear & Tool Works is installed on a vintage rubber mill and yes it is not yellow, but in reading about the mfg, it appears these gear boxes were installed on cranes derricks winches etc. Thusly, if the 'stretch of the request is being begged to be included herein', perhaps a recommendation for the lubricant?
Present lubricant material is reasonably amber although doesnt have the heavy odor that a vehicle rear diff has. Keep in mind: No person says that it is correct LOL.
I had it sampled & analyzed and the recommendation is to change it.
Have also attached some pics of said gearbox. Tis no small item as it is about 4 feet by 2 feet in plan view and about 2 feet tall. Input shaft on one end, and output shaft on the other end.
Some searching for either of the mfg's names yielded this article:

The company Pacific Gear & Tool Works was combined w Western Gear in 1953, giving me hope of finding something to indicate the lubricant....
As an conversational aside on another gear box, we just goofed up and put a AGMA 4 in a gearbox that spec'd a AGMA 5 and it turned out the copper degradation test was a little different requirements. Although the viscosity was correct, other attributes unfortunately were a lesser compliant.
