Stkz anomaly: Bf 109 G-2 JU+XY (FinnAF MT-217)

[Kari Lumppio]

Salut!

Solid data based comments are looked for this Stammkennzeichen anomaly.

In 1943 Finnish Air Force received Bf 109 G-2/R1 Trop* WNr 10357, which was coded as MT-217. The Stammkennzeichen for the plane was JU+XY, which goes against the traditional rules (= JU stood for Junkers).

Finnish unit diary text explicitly ties code MT-217 with code JU+XY. The same code JU+XY is also found from the transferring pilot's flight logbook. In others words two written and independent primary sources.

Yet from German loss lists (BA-MA RL2 III Gen. Qu. 6.) is found accident for the same WNr 10357 (4./JG54 Nov. 6th, 1942 at Demyansk), but Stammkennzeichen given as BG+OM!

Questions:

Is the Stkz BG+OM found in the original loss list or is it an addition by some researcher/loss list creator?

Is there listed any accident/loss for a nearby WNr which would have Stkz JU+XY (and there would have occurred a mix-up)?
(edited addition: What were the Bf 109 losses for the day Nov 6th, 1942?)

Can anyone give any other examples of Stkz JU+X_, JU+__ etc. ?


Not directly related, but does anyone have Stammkennzeichen for Bf 109 G-2 WNr 10522 (FinnAF MT-221) or nearby?


AFAIK due their nature Stammkennzeichen did not change ever, much like US Navy Bureau Number. Something is wrong here and at least I would give the nod for the Finnish sources (note plural). NOTE! Valtonen's book is of no help here as it gives incorrect Stkz.


Comments, additional data etc. welcomed.


Thanking in advance,
