The kit is based on the UNIMOG kit released some time back. New parts were made for the cab - roof and fire control boxes within the cab.The launcher has a number of parts. Each launcher tube has 3 parts and once completed, each individual tube is visible. 86 parts makes up the completed launcher sub section.Extra boxes and fittings were added to the chassis and the over engineered grill is detailed with Photo-Etch parts.The modeller has to construct the canopy, but I have moulded a form / guide for the modeller to use when the frame is done. This is the only part of the model that requires a little "scratch building". It is impossible to mould. I recommend using 0.8mm brass rod for this.
