Here's an unusual one- almost 4 inches long with two tiers. Main stem has 11 slots and the end one has 8. Its pretty large compared to a modern Bramah or even a Cotterill. Does anyone know what type of end caps the nested or tiered keys had? I think it was oldlock who kindly posted pictures of standard Cotterill caps going back a while, but was wondering what style they followed for the unusual tiered keys.
