Back in the day, and a few years before I came along my Dad was in the excavating business. He described a similar lubester to what you have except his had a compartment for a grease gun. Dad said his was made by Bowser. It was situated near the fuel tanks used to fuel the dump trucks and heavy equipment.
No idea on value.
