Which plane did the "Red Baron" earned his name and reputation as a fighter pilot?

Manfred Albrecht Freiherr von Richthofen (2 May 1892 – 21 April 1918), known in English as Baron von Richthofen, and most famously as the "Red Baron", was a fighter pilot with the German Air Force during World War I. He is considered the ace-of-aces of the war, being officially credited with 80 air combat victories.

Richthofen flew the celebrated Fokker Dr.I triplane from late July 1917, the distinctive three-winged aircraft with which he is most commonly associated, although he did not use the type exclusively until after it was reissued with strengthened wings in November. Only 19 of his 80 kills were made in this type of aircraft, despite the popular link between Richthofen and the Fokker Dr. I. It was his Albatros D.III Serial No. 789/16 that was first painted bright red, in late January 1917, and in which he first earned his name and reputation.
