Last of the Breed

The 1949 Key-O-Matic Code-O-Graph was the last offered on the Captain Midnight radio show. To compensatge for the slippage in the 1948 model, the Key-O-Matic had its cipher elements on gears, which, when engaged, could never slip, To change cipher settings, a tiny two-tined key was inserted into slots in the case over the upper gear. A leaf-spring clutch mechanism would cause the gears to disengage to change "Master Code" settings.

The key was easily lost, and perhaps 1 in 20 surviving Key-O-Matic Code-O-Graphs still retains its key.
