Rare Bf 109 K-4 photos

[Marc-André Haldimann]

Hi folks,

shifting through Wydawnictwo Militaria 042 devoted to the Bf 109 K, I was glad to see two previously unknown to me Bf 109 K-4 pictures.

This machine is objectively identifiable thanks to the aft positioned D/F loop as a K-4, found in May 1945 at Peenemünde.

Nothing else is known about this fascinating winter camouflaged Bf 109 K-4 "Schwarze 468", beyond the time frame (Winter 1944 - 1945).

Any ideas on which units did use those machines? Where was the Winter camouflaged K-4 photographed?

All inputs warmly welcomed!
Marc
