Towards the end of the war every available field gun was mounted atop a vehicle to produce a self-propelled anti-tank weapon. In the case of the Sd. Kfz. 251/22, a modified PaK 40 anti-tank gun was built with a trimmed shield so it could be mounted directly on the standard Sd. Kfz. 251 chassis. The gunner would sit on a folding wooden seat to the left of the gun while the rest of the crew served the weapon. Impressive to look at, the design had major shortcomings among them a limited left and right traverse due to the confining space in which the crew had to operate. Furthermore, an overloaded chassis and a structure not designed to handle the strain of the gun's recoil led to many mechanical breakdowns. Sold Out!
