It’s an early mordan lock having only 5 slides - anyone know of another ?
Only modern versions intended for use by landlords to lock out tenants whose were seriously in arrears. Back in the 50’s a lock rep for S&G sold me one only because I was intrigued by the miniaturization of the cylinder and key. Don’t know what happened to it.
I also bought a set of padlock crackers from him the likes of which I have never seen before. The holster also contains spacing blocks to suit a variety of shackle sizes.
