Kodia 1105 (Pearl 2T SS) double-turn mortice lock with 3 keys and a solid brass latch and bolt. Set into the edge of a door, its spring latch keeps the door closed and two turns of the key throw the bolt to lock it. The lock body is charcoal grey, while the latch, bolt and faceplate share a satin silver finish. The faceplate is marked "6LEVERS". A square spindle hole takes the handle, with the keyhole below, and the three silver-coloured bit keys come on a ring.
