Ok, here is my reaction. - Hello Stig, thanks for interest!, but there is fallacy in your statements - going off track in third Line.
I never proposed say other than fuselages be JFM built (and ATG/B&V/DwF), but clarification is below.

But Gerneralizing on factories there most be be just one Factory (SAAB) but in real life there are many Branch factories - One large one is "made in Taiwan" etc.
but you skip meanings and purposes of "Zweigwerk" (Branch Factory) or how JFM operated.

So you need call this JFM built (produced) Ju 52/3m (ex JFW / Ifa built before 1935) - never Bernburg built/produced, because 1937 production was from THREE main Junkers Branch Factories (Ascherleben, Halberstadt and Leopoldshall - and Bernburg was "Competion Center" but also a Zweigwerk FZB, others were FZA, FZH and FZL). FSD was Flugzeug Stammwerk Dessau, but also FSD-M (Merseburg) and others.

Please call them JFM produced, FZB assembled/delivered. This is as exact as possible (in my view). Thanks for showing this interest.

Gerhard,
Yes I have plenty of Ju 52 data(info, but the paper logbooks (covering October 1937 onwards) are all still in storage boxes - because present office is a temporary one - Very cold in winter.

But - I Happen to have pictures of the component and main dataplates on Ju 52/3m g4e W.Nr. 6595 HB-HOT - since 2012 at Reykjavik, Iceland - going on its USA tour -Indeed had Bernburg (Bb5) was stamped on JFM Dessau BAL inspection "main plate" 6.9.39 but it still had its Aschersleben ("Trager Mitte") plates (under Serie 35210.54/16) the Centre-Wing-Stubs at wing-root, that actually seem belong to the Fuselage, and these can be seen already attached on Aschersleben pic in post #4.

And copied from old file of mine (not verified figures) but explaining some beginning and progression of Ju 53/3m production.

The first Luftwaffe orders were planned for in August 1933. It contemplated that production plans for 5,845 Ju 52/3m were to be made (in meaning contracted for) by 01.04.1935.
Deliveries of this contract had already begun when on 09.03.1935 the world press was informed of the formation of the (new) Luftwaffe.
Under the ABC program 179 were ordered on 13.12.33 from ATG (wings), Hamburger Flugzeugbau/Blohm & Voss (tails and rear fuselages), Dessauer Waggon Fabrik (fuselages) and Junkers (final assembly). These were to be delivered in 1934. The aim was to exercise more metal aircraft construction (already started by ordering up to 2,000 Ju W 34 from several building firms).
Further 450 Ju 52/3m (Bombers) were ordered under the Rhineland program. Extending this, further 762 were planned (to October 1936). Further were planned for October to December 1936 (JFM 39, ATG 26). In 1937 (JFM 189, ATG 33). Total Auxiliary Bomber orders stood at 1,130 on 01.07.1937. In 1937 monthly allowance for Transport ´C´ Schools was only two per month. In 1938 (Jan to June) only JFM was scheduled for production (370) but large numbers of Auxiliary Bombers were to be rebuilt to Transport standard (285 by WFG). Until 31.12.1938 an total of 292 transports were planned. Another 1,026 were to be built between 01.01.1939 and 30.06.1941. The ATG assembly line was re-opened in 1940 due to still increasing war demand. Amiot started deliveries in late 1942. PIRT made/assembled 32 machines in 1944.

NB. Further queries or questions from Europe must be made in writing, in triplicate (by older copy methods - copy method found only in museums), X-erox not allowed, and quiery posted in Hard-cover DHL B-Mail (surface mail). That guaratees at least 28 days in delivery to my country, and then suffcent time to answer (which I do not have).
