It is said it was the E-3 Werk Nr.1304 of the 1./JG76. On the 22nd Novemeber 1939 Ofw. Karl Hiera lost the geographical orientation and landed accidentally at the Strassburg-Neuhoff airfield near Elsass. On the 5th January 1941 the plane was crashed during landing at the Farnborough airfield. She was repaired with tail parts taken from another Bf 109E Werk Nr.1480 that was Franz von Werra's kite captured in Love's Farm, Marden, Kent on the 5th September 1940. However there are still doubts about the mending and the Werk Nummer. E.g the cockpit conopy is of E-4 variant but not the E-3 one the W.N.1304 was equipped with. But it could have been replaced quite easy after the crash.
The plane wore the camo scheme made with the Dark Green and the Dark Earth on tops and the yellow one on undersides. Probably , the spinner was of the RLM70. Also the frame of the cockpit conopy was of RLM71 mostly.
The aircraft was tested without armament and the gunsight.
