Here are two cars you don't see very often. Car, Railroad, 8 Wheel, Searchlight, Dummy, Military, Six Inch, Coupler, Tab and Slot. I believe that is how it would be identified in Marx Military jargon. The four wheel dummy searchlight is probably the more scarce of the two. It was included in the clockwork military set with the 897 engine. The eight wheel version is a separate sale item not included in any set.
