Original Item: Only One Available. During the war the enemy was able to triangulate radio transmissions to determine the location of the source. With this information at hand, they would be able direct artillery fire on the position and destroy the radio and take out the unit that was using the radio. The remote control unit was connected to the radio and placed in a distant location away from the position. The remote control unit would be the item that was triangulated and destroyed if the enemy was able to direct accurate fire to that position.

Crosley built RM-29-A Remote Control Units for the U.S. Army Signal Corps. This unit allowed remote communication from a field phone at a front line position to other military units via radio transmission. The RM-29-A was the interface between the phone switchboard and the radio set. The unit could also be used as a field phone if needed.

This RM-29-A still has the data plate attached to the front. The information that can be found on the plate is as follows:

The unit does not appear to have any significant damage to it, however there are some superficial scratches and rub marks that removed a little paint. The switch still works as well as the hand crank. As far as if this thing is still operational in the sense it was during WWII, we do not know nor are we capable of testing it here at IMA.

Comes ready to display in your WWII U.S. Army Signal Corps collections!

THIS UNIT IS STILL CAPABLE OF CONDUCTING AN ELECTRICAL CHARGE WHEN WOUND UP

United States Army Signal Corps
The United States Army Signal Corps (USASC) is a branch of the United States Army that creates and manages communications and information systems for the command and control of combined arms forces. It was established in 1860, the brainchild of Major Albert J. Myer, and had an important role in the American Civil War. Over its history, it had the initial responsibility for portfolios and new technologies that were eventually transferred to other U.S. government entities. Such responsibilities included military intelligence, weather forecasting, and aviation.

Mission Statement:
Support for the command and control of combined arms forces. Signal support includes network operations (information assurance, information dissemination management, and network management) and management of the electromagnetic spectrum. Signal support encompasses all aspects of designing, installing, data communications networks that employ single and multi-channel satellite, tropospheric scatter, terrestrial microwave, switching, messaging, video-teleconferencing, visual information, and other related systems. They integrate tactical, strategic and sustaining base communications, information processing and management systems into a seamless global information network that supports knowledge dominance for Army, joint and coalition operations.
