Half Cylinders for Lockwood Mortice locks ( one half only)

Oval profile cylinder: The shape of a standard lever lock key way in central Europe and more commonly used in Australia  is such so that manufacturers use the same lever lock lock-case as a basis for the Euro lock cylinder. The cylinder is normally fitted with the pins "upside" down, to allow the cam on the cylinder to reach the lever lock mechanism.
