M16 Quad .50 Track Question

I’m finally finishing up my Tamiya M16 halftrack, but I’ve hit a snag.

What are the tracks made of? Metal? Rubber? Metal with rubber pads? Help!

I want to put this one and possibly my Stuart in a little dio, and I’m stuck until you guys can give me an answer. Thanks in advance.

The tracks were one big rubber band that were molded over steel. Only the little stubs on the edges of the tracks was where the metal showed through.

Just the answer I was hoping for, now I can continue with this while I watch Monday Night Football. Thank you, Rob.
