As the focus was very much on the 'Red Baron' von Richthofen, these two books were key in research

"Who Killed the Red Baron" P.Carisella & J.Ryan, 1969
"The Red Knight of Germany", Floyd Gibbons , 1927

The two Spandau's shown were pointed out to me to be identical in form to those on the Red Barons plane 425/17. It was noted to be vermillion red (painted over the light blue color prior).
There were conflicting reports of the final flight and battle, some had said there was ground fire shooting at the same time the Baron was attacked by Roy Brown in his fighter. This was incorrect, and it does not seem that Brown's shots were hits.
Carisella notes "...examination of Richthofens guns found one to have a separated cartridge in the breech, which constitutes a No.3 stoppage which would be almost impossible to clear in the air, and the other gun had a broken firing pin which would only allow the guns to fire single shots so that at the time of his death he would have been out of action. "
further noted that he had come down low, exposing the whole side of his body, conducive to attempt to clear the gun stoppage.
It is noted that the jamming of one gun and the firing pin issue would have permitted only one or two rounds then stop.
The ultimate conclusion was that the Red Baron was killed by ground fire from an Australian gun position as he was low and probably either trying to resolve the issues with his guns or perhaps trying to land to do so.

The attached photo of one of the guns was found to have broken firing pin (695-1795 number). While this part remains of the gun, it is unclear what happened to the pair of guns. They were last seen night of April 22,1918 resting against the remains of the triplane. There was a wild obsession with souvenirs, machine gun belts were cut up and distributed to various Australian units there.....the propeller was sawed into at least 40 sections.
