Hello Artie Bob,

all internal documents doesn't mentioned an G - 6 serieal production after August 1944 .... for example "Programm 226/2" from 20.09.1944, "Programm 227/1" from 15.12.1944 with information from 13.12.1944 about really produced a/c's (the number of G - 6 is equal with number from end of June 1944) and a lot of other original documents.

I believe the G - 6 mentioned by C - Amt were the G - 14 delivered without MW 50 - system. From technical view these a/c's indeed were G - 6 but the prices were different. Erla sold this "G - 6" as G - 14 to RLM, stamped the ID plates with G - 14 and registered these a/c's in the documents as G - 14. Erla had signed an contract about delivery of G - 14 and Erla was sold for G - 14 ... The C - Amt registered the technical reality but this doesn't mean it was an "official" G - 6 NEUBAU production by Erla.

Best regards

All very interesting. I notice that Regensburg noted in its production plans/deliveries report for 4.9.1944 the planned production of 2403 G-14s of which 835 would be G-14s, 200 would be G-14s without MW 50, and 1368 would be G-14ASs.

Slightly off topic, but why would they building G-14s without the MW 50 installation?

[Kurfürst]

I just wanted to ask that... perhaps rebuilds of G-6s? But for what, without boost, at that date...?

Perhaps it is with the intent to deliver these MW-less a/c to conversion centers, to be finished as other a/c, say recce G-8s? MW placement was different there, so it would faciliate things...

It's possible they did not get the MW-50 tanks in time for assembly, rather than letting the output dry down because of a missing part they probably chose to let the G-14s out w/o the tank.

I´ve just seen a photo of a G-14 showing the serial number (464463) that
carries a 87 type fuel stamped on the fuselage which indicates a Db 605 A-1 engine without the MW-50.
Unless it was an AS model; I cant identify the engine cooling.
Was there any "AS" models within this block?

Thank you, Kurfürst and Olivier, for your comments on the MW 50-less G-14s.

Nope,
DB605AM/ASM were also cleared for B4+MW-50.

Well
Accordanly with Mercedes-Benz AG , Archives , Stuttgard in Germany
Db 605 A-1 uses B4 type fuel
Db 605 AM uses C3 + MW 50
Db 605 ASM uses C3+ MW 50
Db 605 AS uses B4 type fuel.

According to several MW-50 documents as well as technical documents pertaining to AM and ASM engine both were cleared for use with B4 after an initial introduction with C3 as the only supported fuel.
Use of B4 instead of C3 was risky in case of a sudden drop of MW-50 injection, the effect being a blown engine due to B4 knocking at such pressures. That was the only restriction as listed in the manuals.
PM me if you need more details.

Sorry to intervene this late, but, speaking of the "MW 50-less G-14s", it may be of interest to note that several were flown by the ANR's 2° Gruppo Caccia.

In fact, the personal agenda of Magg. Bellagambi (CO of 5a Sq. "Diavoli Rossi") had the following G-14s reported as being devoid of "methanol" boost:

W.Nr.464380
W.Nr.464430
W.Nr.464446
W.Nr.464456
W.Nr.464464

As a sidenote, the following one was the only 464xxx aircraft with the MW-50 in the Squadriglia on March 1945:

W.Nr.464480

Hope this helps.
