This is one of many instruments collected by Jack Davidson C Eng FIEE which I have been given by Dr Graham Winbolt. At first this instrument was a mystery until I noted the faded makers initials on the scale plate.

In 1898 Societe d'Electricite et automobiles Mors was founded in France, as was NIF [Netherlands Instruments Factory]in 1900 which became NIEAF [Netherlands Instruments and Electrical Apparatus Factory] in 1913. In 1984 Smitt [founded in the Netherlands in 1902] merged with NIEAF.
