This set includes a soldier talking on a type EE-8 Field telephone. This particular model carried in either a leather or canvas pouch, was used by the U.S. military from 1935 into the Vietnam War. The EE-8 used D cell batteries to power the electric signal that carried the signal through a communication wire to the other phone, with a maximum transmission distance of seven miles. It had a hand-cranked dynamo to generate a charge that would ring the phone on the other end of the line. During World War II the phone was preferred to the radio and the EE-8 was much more reliable than the backpack mounted Walkie-Talkie (SCR-300) or the Handy-Talkie (SCR-536). The phone line, which could be run through a switchboard from a command center, was often run by soldiers during combat situations.1/30 scale Matte Finish 19 piece set in box
