Thanks for posting the 1955 Dealer Display Catalog images. These are very informative, of course, but for those who are planning to use them as a guide to building a replica of the layouts, one has to use caution. Often times what was pictured was not exactly what was produced. For example, the D-147 shows the ZW and controls sitting atop the platform, when in actuality, the layout came with a separate control panel, which was typical for the 5 X 9 displays. Also, the D-148 shows a RW transformer, when in fact, these layouts were shipped with a LW, which was introduced in 1955. More drastic, is the fact that in the catalog, the siding at the "front" of the left hand lower loop is shown as a stub end siding, when the production layouts were made with this as a passing siding. There are many other examples as well. In 1956, the D-165 as illustrated in the catalog was based on a modified D-148, but the actual layout produced was much different! I ended up building my replica on the catalog illustration and thus ended up with replica of the prototype layout, not the actual production layouts!
