I have only seen photos of 52's with no smoke deflectors, and tub style tenders. Also in two colors, black, and photo grey.
The locomotive itself, to me looks just like a class 50. I think, maybe, after the war, these were re-classified by the DB as 51's. As steam power began to cease, the tub tenders went away because of their lower capacity. They were made for war use, because they could be built faster. It's easier to pound or stamp a flat sheet into a half circle, than to weld a box together. Then you weld one surface at each end, instead of also the bottom four sides. you save two long welds along the bottom. I like the class 51 with the brakeman's cab. It also has a Tel-Ex coupler on the rear. Item #37841.

I assume you mean the Class 53 Mallet, Spitzenklasse. We have one in our club museum. Very nice I might add.

Class 52 was built in many different combinations of tenders, colors, countries and smoke deflectors:

Here are some examples from gutzold (tube tender, two sizes of kondenstender, etc),

Just go down to class 52:

I think ones of the most interesting tenders for the 52 is the Streifenrahmentender (very square lines design), as far as I know it was used in gray DRG livery without smoke deflectors and later on in DR livery with smoke deflectors using the traditional red and black colors, no idea if it was used under DB.

I think all BR52 made in Belgium (like Tubize) where put together after the end of the war. They had the parts for more than 100 machines if I am not mistaken.

The ones that served during the war in Belgium where made in Germany AFAIK. When the Germans retreated they left 3 of the BR52 Kondenser behind (of which marklin made a model).

The 'russian' BR52 can be seen in the Speyer Technikmuseum. It has the typical red star on the front.

It's evidently a complicated story. From June 1945 to 1948, Henschel built 73 locomotives and Jung built 11. I can't pretend that I have a complete answer to the question but I found a bit of information in Horst J. Obermayer & Manfred Weisbrod, Dampflok-Report, Band No 3 (Hermann Merker Verlag, 1996), pp. 58-59:

In 1945-1947, under the supervision of the US military government, Henschel completed locomotives 52 1797, 1803-1818, 2869, 2871, 2877 and 2888-2893 to the same specifications as the units built during the war. Arn. Jung built 11 locomotives numbered 52 3321-3331 for the Göttingen Eisenbahn-Zentralamt in 1945-46. All these locomotives had tub tenders (Type 2'2' T 30). Two locomotives were also built for the Rheinischen Braunkohlewerke. In the same period Henschel also built 52 2018-2020 and 52 2022-2027 with short condenser tenders (Type 2'2' T 13,5).

In June 1948 the DR administration for the western occupation zones ordered 70 locomotives of BR 42 and 65 machines of BR 52, all with preheaters. No particular system was specified, as it was intended to experiment with different designs. Postwar increases in coal prices made fuel economy important. The BR 52 order was later reduced to 40 units, all from Henschel. Two locomotives from this order received Franco-Crosti exhaust gas preheaters and were given numbers 42 9000 and 9001. From the other 38 machines (52 124-143 and 52 875-892), four locomotives (52 124-127) had no preheaters, so that they could provide a basis for comparison with the other testbeds. 52 128 had a Knorr surface preheater.

31 locomotives were built With Henschel preheaters of various types. Most had Henschel MVR preheaters and VTP-B 18 000 turbo feed pumps. 52 138 had a Henschel three-drum preheater. 52 891 and 892 had Heinl preheaters and V 10 piston feed pumps. The Henschel preheaters served well but the turbo feed pumps caused continual problems.

The condenser locomotives were all out of service by March 1954. Of the machines with preheaters, 26 were still in service at the end of 1958. They were all withdrawn by 1962.

Cem:

I'm glad you found it helpful. I found a little bit more detail in Jürgen-Ulrich Ebel & Rüdiger Gansfuß, Franco-Crosti (EK-Verlag, 2002), in which there is a table at p. 21 setting out these differences among the postwar-built BR 52s:

52 124-127: no preheater / injectors
52 128: Krupp mixture preheater / piston pump
52 129-132: Henschel MVR with smokebox structure / VTP-B 18 000 turbo pump
52 133: Henschel MVR with smokebox structure / KT 1 piston pump
52 134: Henschel MVR without smokebox structure / TPB 18 000 turbo pump
52 135: Henschel MVR with smokebox structure / TBP 18 000 turbo pump
52 136-137: Henschel MVR with smokebox structure / VTP-B 18 000 turbo pump
52 138: Henschel tube preheater / VTB-B 18 000 turbo pump
52 139-141: Henschel MVR with smokebox structure / VTB-B 18 000 turbo pump
52 142-143; 52 875-890: Henschel MVR without smokebox structure / VTB-B 18 000 turbo pump
52 891-892: Heinl MV / V 10 piston pump
42 9000-9001: Franco-Crosti preheater / KV 25 piston pump

On page 20 there are nice Carl Bellingrodt photos of 52 133 and 52 891. I can e-mail a scan of these to you if you wish.

M. Weisbrod & R. Barkhoff, Die Dampflokomotive - Technik und Funktion, Teil 1 (Hermann Merker Verlag, 1985) has descriptions, drawings and detail photos of injectors, feed pumps and feedwater preheaters at pp. 45-60.

You should also look at Kurt Miska's article about the BR 52 at
http://www-personal.umich.edu/~khmiska/_derived/br52.htm, if you haven't seen that already.

Damon's is a Soviet version.

As far as I know, the Br 52 was a re-hash of the Br 50 but with alterations to speed up construction. Some of the tub tenders seem to have ended up as tankers in MOW service later on - I think Liliput for one offer a pack of two of them as emergency tank wagons.

The Allies did the same - Britain had the "WD" (War Department) 2-8-0 and 2-10-0 heavy freight locos which were intended to go into Europe post D-Day to replace damaged locos. They had numerous little things like cast (solid) wheels on the leading truck that were either quicker to build or used fewer scarce resources.

Ladislas hi,

Thanks for the correction and the pictures.

Gert hi, I have the war gray AND the condensing tender Br52s too, I now need a regular Br52 with Witte deflectors :) I think 429000 counts as Br52 - after all, it IS a Br52.

For those who are interested: few months ago a TCDD Br52 is fixed and run after 20 or so years. What an excitement! And yesterday it was here in Istanbul. Here's the link to the photos:

Very nice picture, Bert.

Yeah, I've just seen the link and gone through it. Will open a new one for I'm such an idiot

What a blasphemous e-mail address you operate!

I'm silently hoping for a 4MFOR version of this one, with some panzers .

Are there any 3R HO models available with this tender?
