1940s Worthington Gamon Meter Co. Cap Newark New Jersey NJ #1790701

Description

This is from my parents' estate.
It has one of the lowest numbers I've seen.
It measures 3 inches in diameter (without the screw hole extensions).
Condition:
I believe that Dad had this refurbished in the 1970s, but I'm not sure.
It's in good condition.
Some of the green has returned on the underside.
Stored in a non-smoking environment.
