This nice N gauge locomotive by Fleischmann is 7123 a DB BR 23 steam locomotive in black livery with running number 23 105. 

The steam locomotives of Class 23 were German passenger train locomotives developed in the 1950s for the Deutsche Bundesbahn. They had a 2-6-2 wheel arrangement and were equipped with Class 2'2' T 31 tenders. They were designed to replace the once ubiquitous Prussian P 8 engines that had been built between 1908 and 1924 and, in their day, were the most numerous post-war replacement class. The locos were manufactured for medium passenger train and light express train services.  No. 104 was the penultimate steam loco to go into service on the DB network. 

A number remain in preservation. 

The loco is in very good condition as you can see in the pictures, it is 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 our other listings, we typically have various HO and OO locos on offer as well as an extensive range of imported N gauge locos and other items. 

Note: We 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!).
