Over on the Tinplate Forum I made a post just now about an interesting Elettren product: tinplate models of the antiaircraft cars that accompanied the special trains used by Hitler and Göring. There were a fair number of these built in 1938-40, in three tranches but to a more or less common design, of which their length at 26 meters, longer than the passenger cars they accompanied, was one notable feature. After the war at least two of the cars, reputedly from Göring's train, ended up in Austria. By 1963 they had been extensively rebuilt and shortened into a pair of 2nd class coaches with nine compartments, rather indistinguishable from the other coaches of contemporary prewar build the Austrian Federal inherited in a more straightforward manner. Here's a photo I took of one of the pair:
