I have the original blueprints of this tank and your family and 2 marders of revell in 1/72, but never build one.. hehe. The blueprints is lost for the Army of my country, but I have the originals. This is from one old friend collection, who obtein of the TAMSE enterprise how received to a gift in 1981 and in 1998 give me how a gift. He have one firm of models in metal named NAHUEL and build the TAM in metal. This is one part of the scan (the beast is in 1/25 and 1/5 scales).
