Pair of battery-operated mobile field phones, made in Hungary during the Nazi occupation, in original Bakelite cases with carrying handles. Serial numbered cases contain a handset which plugs into the case, a battery (one missing), hand crank, wiring diagram, and a coil of wire. Phonetic codes molded into top of case. Though I haven’t tried these, they appear to be in very good working condition. Quite heavy, each case measuring 11 1/4" long, by 7 3/4" high, by 4" wide.
