This very nice HO gauge locomotive by Fleischmann is 4174 a DR BR 50 Steam locomotive in black livery with running number 50 008.

The DR Class 50 is a German class of 2-10-0 locomotive, built from 1939 as a standard locomotive (Einheitsdampflokomotive) for hauling goods trains. It was one of the most successful designs produced for the Deutsche Reichsbahn. This class was procured as part of the preparations for the Second World War. Up to 1948, 3,164 Class 50 engines were built by almost all the European locomotive factories – towards the end as so-called provisional war locomotives (Übergangskriegslokomotiven)

At the end of the steam locomotive era, they became virtually a universal class of mixed-traffic steam engine that, thanks to their low axle load, could even be employed on branch lines with light track beds. The Deutsche Bundesbahn grouped the locomotives into Classes 050, 051, 052 and 053 from 1968 so that the numbers were computer-compatible.

Some of the class were used by the Polish State Railways as type Ty5.

A number remain in preservation some in operational condition. 

The loco is in excellent condition as you can see in the pictures, I have not tested it but I can see no reason why it would not run, so it it is sold in untested condition,, but a complete external visual inspection has shown no reason why this loco would not run and 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!).
