A question about Sherman tracks

The rubber has burned off.  What you are seeing is the metal "skeleton" of the track that the rubber is vulcanized around.

Thanks!

So, my Dragon M4A4 has T-48 tracks, I believe (I'm new to this, but try to do some research before asking questions). A look at a Sherman Track web page (cool cuz it has pictures) shows that one, and it's rubber. So it's all correct, I hope for this particular tank. I can't see what is on the museum one, and they might not even be otriginal.

Thank you for the help!

Sherman tracks (except for the CDP ones) were interchangable.    The Latrun AMX shows an M4A4 chassis with T51 smooth face rubber tracks.  The burnt skeletons were appropriate for those tracks that were all encased in rubber (T41, T51 and T48).  Others were all metal or composite metal & rubber and would look different if burned away.  A plastic set of burnt skeletons is available from Panda Plastics.
