Small lithographed tender loco with clockwork mechanism. Gauge is 25mm. The No. 7148 Loco was probably made by Issmayer for Schoenner. Please see the image that shows a page from the Schoenner catalogue depicting the range of cars that were available with this particular loco. 

Please see my other offerings of early, quality toy trains available at this time. I will combine shipping on multiple orders. Your satisfaction is important to me so if you are dis-satisfied with any purchase that you make from me, simply return it for a full refund. My area of interest is in toy trains made in Germany before WW1, particularly for sale in the American market. Bing, Marklin, Carette, Schoenner, KBN, Ernst Plank, Issmayer and other makers are of special interest.
