Visitors to this site are urged to compare the picture below with the picture shown under the "DS" heading. It will be seen that these two pictures are identical, except for the roof. Only the roof was changed from the nickel plated iron parts (of the IM series) to metal supports covered with "roof stones" (of the Dach Steine, or DS, series). Even the backgrounds are the same. As will be seen in a subsequent "issue" of this page, the new DS bridges were slightly longer than the Im bridges, so the background had to be extended to accommodate the longer bridges in the DS designs.
