BP+FO, W.Br. 7204

[Nick Beale]

I have an ULTRA reference to this aircraft from March 1945. The Stammkennzeichen seems to fall with a block of Siebel Si 204's (and ithat fits the context) but can anyone confirm its identity?

[Matti Salonen]

I have Si 204 D-1, WNr. 321281, BP+FO. I have no Si 204 with WNr. 7204.

Matti

[Nick Beale]

Thank you Matti.

This was from an ULTRA message (CX/MSS/R483(C),21:

To AMC [Air Movement Control] Unterschlauersbach from AMC Lechfeld, dated 4/3 [1945]:
Request landing report of 7204 BP+FO. Took off from Lechfeld at 0735/(smudge)2.

So I wonder what "7402" meant if it wasn't a Werk Nummer? Another aviation mystery!

Read it 7-204, which suggests Si 204 in some code I guess. There was 8-109, but I do not remember if 8 denoted fighter aircraft or aircraft,

8- were airframes and 9- were engines but thank you Franek because you inspired a thought that gave me the answer. Maybe the cipher clerk read "Siebel" as "Sieben" (= seven)?

[Franek Grabowski]

Possibly, unless there was another code for such communications.
I wonder, do you have complete aircraft traffic in Ultra?

No, just a part of what is there for 1944–45, a few things from late 1943, items from Summer 1942 that related to my Kommando Koch project, one message from 1941 … there are hundreds of thousands of items from the Luftwaffe and army, even before you get to the naval material (which often links to Allied or German air operations) or the police and intelligence services’ signals (which I have looked at but are very hard to find anything specific in; they are in German and are mostly from and to callsigns whose meaning I don’t know). I haven’t seen the Reichsbahn traffic at all but I believe there is some.

Confess I was impressed by Nick's lateral thinking here.

Sieben 204 (is 7204)

Siebel 204 is just that, the aircraft type. Also it STKZ was used upon landing.

Why didn't I think of that?

Cheers

Could it be the last 4 didgits of o a si204
Like Bu181 BN+OT Wrknr 16170 LSK4 43-44 the picture has the plane with the last 4 didgits 6170. I can imagine germans using the visable number in their communications

As per Matti's answer we know that BP+FO was WNr 321281 and nobody (so far) has ever heard
of a Si 204 with Wnr 7204.
