Scott, I am sorry about not getting back with you before this. The models you were looking at were from a toy company called Micro Machines. They had a series with WW1 biplanes and tanks. There were a couple of tank types. This one and see the link below for another example. They are no longer on the market, but you might find them on ebay. http://www.wingsofwar.org/forums/alb...pictureid=4747
