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?

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

Matti

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)?

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

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.
