Crusader tanks were used by the British in the deserts of North Africa in World War Two.
Paul Heiser Models is making this great model in HO scale.
Until the last few years their have been very few HO scale models of British tanks. These models go a long way in making up for that.
Also from PHM is the HF-7, WWII German steel wagon. The upper one with the V shaped tongue is vehicle drawn and the other one is horse drawn. I have seen German halftracks towing two of these behind them. They were an excellent wagon, but heavy. Sometimes they would have the regular four horses augmented by two more. Sometimes they even had dozens of men pulling them. This was a great wagon for Western Europe, with a good road network, but it had a lot of trouble in the mud of Russia.
