LOCKS No. 6


Used in public Coin Collecting boxes from 1931 until the introduction of the electronic payphones around 1988.

Subtle differences do occur and the obvious difference is the position of the case screw fixings, which were not on the front of the lock on early variants.

Fitted to the cash box compartment cover and different keys were allocated to each lock.

These are tough locks and liable to break a drill bit.

Drawing - CD224.
