ok, what available are Original FIELD OF ARMOR Panther wheels and tracks. of 5 sets 2 could be purchased very reasonably.
I have used these on two Jagdpanther designs and with boring and bearings these wheels are strong enough to support 300lbs total weight.
Tank and Human used with a suspension equipped vehicle, I also have a very old vacu formed 1/6 KVI kit I do not even know the brand of, the local Hobby shop had it in stock when they moved after 20 years in the same location . I aquired it from them.
