Notes

This meter was made by Sangamo Weston Ltd in Enfield, Middlesex, England between 1946 and 1953.

The company was founded in 1921 under the name "British Sangamo" as the United Kingdom subsidiary of the "Sangamo Electric Co." of Springfield, Illinois, USA and was first concerned with the manufacture of integrating kilowatt hour meters and later expanded its activities to include industrial time switches.

In 1936 British Sangamo acquired the "Weston Electrical Instrument Co." of Surbiton, Surrey. This company was the United Kingdom subsidiary of the "Weston Electrical Instrument Corporation", of Newark, New Jersey, USA, a company founded by Dr. Weston (a pioneer in the field of electrical measurements), and recognized as one of the worlds leading manufacturers of electrical measuring and associated equipment.

The resources, knowledge and expertise of the two companies were combined to form "Sangamo Weston", a company with considerable scope for design and manufacture of a wide range of electrical measuring and control equipment.
