I don't know much about it as I am not well versed with radio equipment. I'm not sure if it is an attenuator or sliding match calibration tool. It came out of storage from an old AT&T Long Lines/ Western Electric tower building. The AT&T Long Lines microwave communication system is an impressive, nation-wide network of line-of-sight microwave towers that were used during the cold war era for domestic and military emergency communications. The AT&T Long Lines buildings and towers were designed and built by exceptional American workers and technicians to very high standards of craftsmanship and performance. Should a nuclear attack on the USA have occurred, these towers would carry emergency military and civilian communications including ballistic missile early warning functions. This infrastructure was built to endure nuclear bomb blast and many of these installations had multi-story and underground shelters that were self-contained and served as fallout shelters and emergency bunkers that could sustain the radio technicians that operated the system in order to provide America an on-line emergency communication network during nuclear war.
