I have a piece of test equipment made by ELECTRO Products Co., New York City. No model # on unit. Has labeling on front "The Trouble Shooter". Maybe made in the 50's?. Appears to be a capacitor tester. Has a round meter at the top of the unit measuring both MMF and volts. Middle section of unit has a neon lamp. Bottom section of unit has a 3 position switch labeled "Hi Frequency", "Leakage" and "Meter Test". An operations/parts manual would be great.
