As I'm sure you know, Jochen, the following notes are made to specify that JG 50 aircraft were lost on Wilde Sau operations:
23 Sept 1943: WNr 15625: Flugzeugführer von 7./JG 301.
27 Sept 1943: WNr 15409: Flugzeugführer von Stab III/JG 301.
27 Sept 1943: WNr 15551: Flugzeugführer von 7./JG 301.
22 Oct 1943: WNr 140066: Flugzeugführer von 7./JG 302.
As you probably also know, it was due to the hazardous Wilde Sau missions that Alfred Grislawski had his beautifully decorated rudder removed from his JG 50 Bf 109. Thanks to that - and to lots of other very helpful people - it can now be viewed next to Hermann Graf's rudder in a totally unique display at Technikmuseum Speyer. See this web page:

Keep up the good work, Jochen! Looking forward to the next book in the Jagdfliegerverbände series!
