Gray 13A 4
Gray #13A portable 5 cent coin collector with carry handle. When the operator asked for a deposit a nickel would be inserted which would strike & ring a bell. The sound of the bell would resonate through the case, then through a connecting arm into the phone and would be picked up by the transmitter. This coin collector was found with a virtually NOS AE 40 in Wisconsin. View my article Gray 13A Coin Collector
