17GW491 Two Spandau IMG 08 were fitted to the cowling of the Fokker Triplane. On the Red Baron's last fight one of the weapons had ceased to function and the other was misfiring because of a split firing pin. Lieutenant May would likely have been shot down had the guns been working. Richthofen had released his harness and was working to free the mechanism when a single bullet fired from below fatally wounded him.
