This is a field trial prepayment type mechanism.  The installation is equipped with a special latch-in multi-way plug and socket so that, when the mechanism is swung out for inspection, test or adjustment, the electrical circuit remains continuous.  Apart from the association of this latch-in plug with the mechanism (and the need for a bell-set equipped with the corresponding latch-in socket, i.e. a Bellset No. 42), there are no other differences between this coin-box and Box, Coin-collecting, 14D, complete.

The mechanism, equipped with the latch-in plug, is coded Box, C.C., Part: Mechanism, No. 17.

Two types of mechanism were produced, type A and type B.

Type A with connector plug disconnected

Type B with connector plug connected
