the tracks of the T-55 and Elefant are from Kenny Kong, if the E-100 will come some day from Hooben. Kenny will make them too but it seems that Hooben will never bring the E-100 because of its bad experience with the T-55 and Elefant sales.
But we shall will see about the plastic tracks of the Hooben E-100 I have asked them a lot but they only have this prototype

Of course if we get some people together Kenny will make them for us. But it's not so easy to arrange a group sale.
