"This indisputably fine piece of machinery is the Mk,III and features new improved steam pressure controls than the MkII.  An extra chamber for those inconvenient moments when time is pressing and an all cherry wood handle for smoother gripping and a firmer cocking system."
The Liberator is a large heavy piece and when mounted on its Stand which is  heavy metallic and ornamental it looks really impressive.
Included in the box is the mystery envelope which is to be opened only by the new owner.  27cm
