Excellent piece of kit though. The Germans certainly showed some inventive flair for creating various ways around the Versailles Treaty. The kettenrad was one of those pieces of kit you either loved or hatex. As far as models go, there are some pretty rubbish ones, Tamiya, and some good ones, Das Werk, and the 1/6 scale Italeri versions. Dragon did a 1/9 scale model but it didn't get the positive feedback it deserves and was shelved! I seem to remember a kit I had with a signals Kettenrad with two large cable reels mounted on the body. Cannot remember the manufacturer though.
