Do 335 A-10, A-11 or A-12?

[Roger Gaemperle]

Thank you all for the information you provided. Apparently, there are some conflicting sources.

Smith/Creek mention the Industrie Lieferplan 226/2 dated 22 September 1944 on p.53 in their Do 335 book:
A-10: based on the A-1, built at Dornier Löwenthal
A-11: based on the A-1, but built by the Luther Werke in Braunschweig
A-12: based on the B-6, built by the Luther Werke
A-13: based on the B-4, built by the Luther Werke

On p.64 they mention a TLR document dated 1 November 1944 that confirms that the A-10 were to be built at Löwenthal, while the A-11 and A-12 were to be built by the Luther Werke.

On p.86 they show an extract from the Lieferplan dated 15 November 1944:
A-11: conversion of the A-1 with DB 603 E/G, Luther Werke
A-12: conversion of the B-6 with DB 603 G, Luther Werke
A-13: conversion of the B-4 with DB 603 L, Luther Werke

The completed trainer Do 335 were probably all conversions from A-0 aircraft that were fitted with the DB 603 and were most likely converted at Oberpfaffenhofen (maybe except the first 2, V11 and V12). They were most likely A-10 subtypes. But the Lieferplan 22 Sep 1944 stated that they were conversions from A-1 and built at Löwenthal. If we assume that Lieferplan from September was outdated already by winter 1944 in terms of designations of subtypes, there is still a conflict with the information based on the RLM Flugzeug-Programm Nr. 227 from 15 December 1944 (provided by Seaplanes above), which states that the A-10 was fitted with 2 x 603 E.

Quite confusing. I assume that designations for subtypes changed from 1944 to 1945 and some documents related to planned aircraft, while others to actually built aircraft.
