[INM@RLM]

Going back to post #1 here and the link to Hyperscale Forums with the 12-Jun-2025 post from Lynn Ritger with the words "Would now be a good time to point out that Mimetall didn't build a single Fw 190 D-9?"
In support of that position LR posted a German document showing the Fw 190 delivery position at 31-Dec-44.

A few clarifications:
Mimetall delivered no Fw 190s during 1944, but they did in 1945.
The first Mimetall Fw 190 deliveries were of 64 D-9s in Jan-45. The relevant Beitrag document setting out the Jan-45 aircraft deliveries can be can be found in BA-MA RL 3/1278.
As to how Mimetall fitted into the overall Fw 190 D-9 program, in this January report the Fw 190 deliveries from Con Aslau, WFG & MME are sub-totalled together and against the WFG/Weser figure is the handwritten note "ARB GEM".
A reasonable interpretation is that all three sources were grouped together because all were actually Arbeitsgemeinschaft Roland enterprises, and this grouping then provided an actual total that could be compared directly with the total Fw 190 D-9 planned for the month from WFG in delivery plan LP 227/1.

That MME/Mimetall was indeed also under the Arb.Gem. umbrella is also indicated by a progress report on aircraft deliveries made in the first Dekade of Feb-45 that is found in BA-MA RL 3/1047. This makes separate mention only of these Fw 190 production sources:
FW
Arb.Gem.
Ago
GWF
NDW
ArW
Note: no separate mention of MME/Mimetall.
The Arb.Gem section of this report also includes the words "Sonderzug mit Rümpfen soll spätestens am 12.2 von Nordenham nach Erfurt abgeben" (A special train carrying fuselages is scheduled to depart from Nordenham for Erfurt no later than February 12).

So, I have to modify my earlier thoughts some since it is pretty clear from the evidence above that MME was indeed part of the overall Arb.Gem. Roland activity, but was separated from the other WFG/Weser portions in being assigned a separate prefix-50 WNr. series. The reason for the introduction of the additional prefix was clearly because the volumes expected could no longer be accommodated by sub-dividing further the prefix-40 sequences, and self-evidently 50 comes after 40.

Bottom line: the LR statement in his 12-Jun-2025 post to the effect that MME delivered no Fw 190 D-9s is incorrect, and should never be quoted as being accurate.
