This is a vehicle from the new John Jenkins Designs series on the Spanish Civil War. This vehicle is a German PzKpfw 1A tank numbered 423. Two versions of the Panzerkampfwagen 1 tank were shipped to Spain to fight in the Spanish Civil War. These were the A & B versions. The designs were pioneered by Krupp in the early 1930's. These tanks had several weaknesses including thin armor against anti-tank guns used by the Republicans as well as lightweight weapons (two machine guns). The crew consisted of two men who worked in cramped conditions.
