This oscillating piston water meter with frost-proof bottom and serial number 1,158,957 fit a ⅝” pipe. It was made by the Well Machinery & Supply Company in Fort Worth, Texas.

The Well Machinery & Supply Company acquired California Meter soon thereafter, and advertised Calmet water meters as “A Texas Made Product.”
