The kit is labelled "3 in 1" and offers alternate choices for travel or firing modes, the choice of Canadian Mk.C2 or British Carriage Mk.II for the gun platform as well a choice of manual or electric control types. You need to make your selection before commencing as there are different parts for the carriage and control types, you can also build the kit with or without the gun shields fitted.

Added to that you have a choice of 2 types of barrel travel lock, automatic loader hoods plus the simple double ring sights or the British-designed Stiffkey sight, this all means there are some parts left over depending on the version being built.

The kit consists of 291 parts in beige plastic, 18 small wing nuts in light grey plastic, 1 metal spring, 81 etched parts plus the decal and instruction sheets.
