Kurt Welter had a nocturnal skill that was unique: by the end of the war, he had shot down more Mosquito aircraft than any other Ace, and he did so with mostly non-radar carrying aircraft, including the Bf109 G-10. This rudder represents that 109, with a score at 33 kills.
Welter would soon transition to the Me-262 and continue his nighttime rampage over Germany. The Allies found that the darkness could hide them, unless Welter was in the skies.
Welter's score has come under scrutiny over the years, as the normal method of witnessing kills was not available during night ops.
Full sized, this rudder stands at about 54" tall and shows the kill markings and colors of a unique camouflage pattern found on 109s in late 1944 and 1945, when aircraft component construction was dispersed.
This item appears to show wear, like so many surviving relics now appear.
