The box and certain components have been repainted directly over the WWII paint and stenciling wich is visible from some angles through the current paint which im guessing is from right around 1957 all parts are stamped signal corp as well the WWII stenciling shows this as a signal corp detector throughout its life.

Some bonuses are the WWII dated GM vacuum tubes and the other item that is used for finding and removing the mines.

The bag is the rubber ear pieces for the headset all nos 1957. There are still has all the earth pieces which are still plyable.

This particular detector has been waterproofed at some point in its life.
