Rockwell Water Meter

Description
This is a ⅝” sealed register, magnetic drive disc water meter made by the Rockwell Manufacturing Company. It has a bronze case with a frost proof bottom. Rockwell introduced its sealed register model in 1957, describing it as “the first major advance in water measurement in the past 50 years,” and claiming that the use of a magnetic force to turn the registering mechanisms “eliminates the need for a stuffing box, and makes possible an hermetically sealed register that stays clean, dry, and free from fog.” This example is serial number is 21,000.

Can you tell what year the meter is made by the serial number?

I do not, unfortunately, have correlations between water meter serial numbers and dates of manufacture.
