Hello! My father handed me this and asked if I could look it up (he's 84). He's good at finding random things either in the barn or cellar (or side of the road) and asking me to look up. I haven't been able to find this one though. The dial itself appears to maybe used to count either, at least we're guessing, how much was taken out or added to whatever it was attached to. With think it may have been something from my grandfather's oil truck (drove one in the 1930's and 40's) but my father doesn't remember where this initially came from since he had it hanging in the house for awhile. I've already contacted the Smithsonian archives to see what they could find in there but none of the catalogs they have showed this. Any help is appreciated (and my dad thanks you!)
