Nice WWII era Signal Corps Test Set EE-65-G for maintenance of ground communications. The tag reads " CCN NOM 44911". I know little or nothing about this instument, I found this information on the internet. The tester measures approx. 11 1/4" x 9" x 7 1/2". It is in very good original condition with only light expected wear from use, otherwise no cracks, no breaks or repairs. Items will be shipped USPS and insurance is required.
