WW2 Hickok Model I-177 Radio Valve Test Equipment

A vintage WW2 Hickok Model I-177 Radio Valve Test Equipment / Dynamic Mutual Conductance Tube Tester.

Made by Hickok Electrical Intrument Company, Cleveland, Ohio, USA, it is in pretty good cosmetic condition with a few blemishes, scratches and scuffs commensurate with age and use.  All the controls operate smoothly but it has not been tested, as it is a 110v unit, and is sold as seen.

Built in to a metal travel case with metal latches and a brown leather handle, it also comes with its original operating instruction booklet and test data pamphlet.
