Interesting picture and I started digging around using Google -
There is a company called Ford Meter Box ompany (no relationship to Ford Motor Co.) located in Wabash Indiana.
SO, I did a search for Ford Meter Lifter Tool - and behold out came the following product. . .
Meter-Box-Curb-Tool
It appears to be a plumbing tool.
More info on Ford Meter Box -

Interesting also that these tools have been sold on eeek-bay as "Model T Ford" valve lifter tools.
The tip that something was wrong - the five point lug pattern.
