1920s-30s Jewell Electrical Instruments A.C. Voltmeter 0-3 Range Panel Meter

 A vintage Jewell Electrical Instrument Company A.C. voltmeter gauge, specifically a Pattern No. 190 model. The device measures alternating current (A.C.) voltage on a scale from 0 to 3 volts. 

Details

Manufacturer: Jewell Electrical Instrument Company, founded in Chicago, Illinois.

Time Period: The company produced meters from 1899 until 1931, when it was acquired by Weston Electrical Instrument Corporation. Similar items are often dated to the pre-1930s era.

Function: It is an analog panel meter designed to measure electrical potential difference in alternating current circuits.

Markings: Key markings on the dial include "VOLTS," "A.C.," "PATTERN NO 190," and the manufacturer name around the edges. 

This gauge is primarily of interest to collectors of antique scientific instruments or those involved in "steampunk" projects.

The Jewell Electrical Instrument Company A.C. voltmeter Pattern No. 190 likely dates to the 1920s or early 1930s. 

Key Dates

1899: Jewell Electrical Instrument Company was founded in Chicago, Illinois.

1920s: Meters of this type and style were widely used in radio service equipment during this decade. Advertisements for similar Jewell "Set Analyzers" (like the Pattern 199) appeared in radio publications around this time.

1931: The firm was acquired by the Weston Electrical Instrument Corporation of Newark, New Jersey, and the Chicago operations were closed in 1932. 

This specific model therefore likely falls within the 1920s period when the original Jewell company was an independent and active manufacturer of such panel meters.
