Loss of Me 262 A-1a WNr. 170305 9K+BB on 6 February 1945?

[Karoband]

Good afternoon,

Jan Horn is definite in referring to Me 262 A-1a "Werk-Nr. 170305" as 9K+BB in Das Flerschaden-Geschwader, (2010). It is mentioned on p. 181 (11 Nov 1944), p. 218 (1 Jan 1945 flown by Gruppenkommandeur Major Unrau, and p. 222 (both 4 Jan and 6 Jan 1945).

Then, on pages 235 and 236, for the day of "6. Februar 1945" in the "Starkemeldung der I./KG 51 fur diesem Tag um 16:30 Uhr an den Stab/KG 51" under "Starke-Abang" is found "9K+BB abgeschossen". In the appendix Verluste im KG 51 on p. 362, Me 262 A-1a 170305 9K+BB is given as 100% Bruch but under the place and cause is the word "unbekannt" and there are only question marks for the pilot.

Is anything further known about the loss of 170305?
