The General Radio 650-A is an impedance bridge introduced in 1933.

Frederick Van Veen writes:

The most noteworthy introduction of 1933 was the Type 650-A Impedance Bridge, the work of GR engineers Horton and Field.

Priced at $1751, the 650 was one of the most successful instruments in the Company’s history, remaining in the GR catalog for the next quarter century.
