| This Vietnam era military cord switchboard works quite well. It is connected to several phones, CB and magneto. Also one trunk connects to my Mitel SX-100 PBX.
——
The jackfield has 30 jacks. All have a selector switch for M, C, and T. M = Magneto, C = Common Battery, T = ? (does not work with trunk). Jacks 29 and 30 are marked for CO Trunk.
——
The case becomes the stand for the switchboard.
