Thanks very much for posting the photo and the information here.
A wonderful engine, representing a really special Nuremberg/Nürnberg toy (steam) manufacturer.
I would love to add one of these two-cylinder engines to my small Carette collection. There are only few other engines to beat this one, e.g. a Carette two-cylinder with reversing mechanism (or, of course, the legendary Carette "Industrielokomobile", but that one is even more out of my personal price range...)
I also remember vividly that it took me quite some time (and some slanting autumn sun rays) to find the trademark embossed in the wooden base. I do like the story behind this engine. Thank you again for sharing it.
All the best from southern Germany
