This HO gauge locomotive by Fleischmann is 4139 a DR BR 03 steam locomotive in black livery. It has the running number 03 140. 

The Class 03 steam engines were standard express train locomotives (Einheitslokomotiven) in service with the Deutsche Reichsbahn. The Class 03 engines were built between 1930 and 1938 as express train locomotives. Locomotive number 03 154 was equipped with a parabolic smokebox door, a tapered driver's cab and driving gear cover plates. Number 03 193 was given a wine-red, streamlined, full covering and a 2′3 T 37 St tender, in order to replace the Class 05. 03 204 and 03 205 had driving gear cover plates for experimental purposes.

In 1968 there were still 45 units, now designated as Class 003, remaining in the operational fleet. They were stabled at the following locomotive sheds: two at the Braunschweig shed, six at Bremen Main Station, 13 at Hamburg-Altona, one at Husum, 16 in Mönchengladbach and seven at Ulm.

The last ten locomotives of Class 003 were on duty from 1971 at Ulm; in 1972 the last ones, nos. 003 088, 003 131 and 003 268, were withdrawn from service.

The DR in East Germany had 86 engines in its fleet. 

The loco is in good condition as you can see in the pictures, it is fully tested and runs with working lights. 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!).
