For your consideration is this World War 2 vintage control unit.
This is dated 1943, as can be seen in the photo of the rear plugs.
This is in good condition and powers on. I do not have the proper equipment to test this unit beyond that. The power cord is still [pliable and seems to have good coating.
There are 3 dials on this unit; a General Electric RPM gauge, Standard Electric Time revolution gauge, and a Standard timer.
The measures about 15″ x 5″ x 6″ and has a carry handle at the top.
There are no markings or plate saying what model or manufacturer this is, and I do not know its application. An online reference did note that Standard Electric Corp. departed from clock building and built many items for the military during the second world war, so that along with the date lead me to believe this had a defense or war effort application.
Please see photos for more detail.
