Very nice condition! Does seem to work. Marked Medical Department. The Addressograph Model 70 is the medical imprinter that used the notch on the WWII military dog tags, this "notch" was actually a "locating notch" and is referred to in both Addressograph and government documentation as "locating notch."  The Model 70 was issued to medics in the field during WWII.  The purpose of the Model 70 was to allow the medic to take a soldiers identification tag and transfer the information on the tag to medical documents by imprinting the text directly onto the document.  The Model 70 would accept a notched dog tag and would then transfer the information on the soldiers dog tag to medical paperwork in the field.
