This really nice HO gauge loco by Liliput is a DB BR 18 / Baden IV h steam locomotive in DB black Livery. It has the running number 18 322.

The class IV h (four-h) locomotives of the Grand Duchy of Baden State Railway (German: Großherzoglich Badische Staatseisenbahnen, G.Bad.St.E.) were express locomotives with a 4-6-2 (Pacific) wheel arrangement. They later passed to the Deutsche Reichsbahn, who classified them as class 18 3.

The locomotives were ordered in 1915 and were delivered in three series between 1918 and 1920; they were allocated to the locomotive depot (Bahnbetriebswerk, Bw) at Offenburg. They were used on the Rhine Valley route between Frankfurt and Basel, among other things, in powering the Rheingold. Due to the incomplete conversion of the Heidelberg terminus station to a through station, the planned service could not be implemented without changing locomotives. The locomotives could easily move a 650-tonne (640-long-ton; 720-short-ton) train on the level at 100 km/h (62 mph)

When the last IV h were delivered in 1920, the Badische Staatsbahn had already merged into the Deutsche Reichsbahn. They took over all twenty locomotives as class 18.3 and gave the three series the fleet numbers 18 301–303, 311–319 and 321–328.

During their service with the Reichsbahn, the locomotives were very unpopular with all parties involved because of their unusual four-cylinder compound drive. The engine drivers couldn't cope with the complicated structure; the operations management saw problems with the combination of high and low pressure cylinders.

Towards the end of the 1920s, the locomotives in Baden were replaced by standard class 01 locomotives and used further north. In 1933 the first locomotives came to Koblenz, where they served as a reserve for the Rheingold and ran as scheduled on the Saarbrücken – Frankfurt route. From 1935, the IV h were to be found in Bremen; from there they were used on the north German lowland routes, for which they were well suited. Here staff got along better with the locomotives; and after some detail improvements, it became clear that the IV h was even superior to the class 03 locomotives that were 15 years younger. From 1942, all locomotives in the series were stationed in Bremen.

The remaining 19 locomotives came to the Deutsche Bundesbahn after the war and were initially withdrawn in 1948 as a small class of non-standard locomotives. The Deutsche Bundesbahn also needed fast locomotives for test purposes. Since the newer standard locomotives were needed in operational service, it was decided to reactivate three of the already retired IV h. The choice fell on three locomotives: 18 316, 18 319 and 18 323

The 18 316 and 18 323 were not retired until 1969; they were the last four-cylinder compound locomotives of the Deutsche Bundesbahn. The two locomotives were preserved as monuments: the 18 316 came to an amusement park near Minden; the 18 323 was set up in front of the University of Applied Sciences Offenburg.

The loco is in good condition as you can see in the pictures, it is fully tested and runs with working lights. A complete external visual inspection has shown the overall condition is very good. It comes complete with its box. The box is in good if slightly shelf worn condition. 

Overall this is a really nice scale locomotive and would look fantastic on a layout.

Do please have a look at my other listings, I typically have various HO and OO locos on offer as well as an extensive range of imported N gauge locos and other items. 

Note: I do recommend all locos are cleaned & serviced, as they have some age to them even if the quality looks at the highest level (fairly standard advice for all locos!).
