This is the Twin Forty Tank from the Renwal Blueprint Models collection. This 1:32 scale plastic model kit is from Revell. Produced from 1952-1959 as anti-aircraft artillery, the twin 40mm Bofors guns of the M42 "Duster" were designed to sweep aircraft out of the sky. With the advent of jet engines, however, it became increasingly difficult to down planes. So the army did what it does best, it improvised. On the battlefields of Vietnam, the Duster was pressed into a point-defense role. Few enemies wanted to confront the awesome firepower of the Duster which could fire 240 40mm shells every minute. Kit features five figures, interior detail, storage bins, and tool pack.
