A couple of observations.
On closer inspection of the picture of the children sitting on the Tank, shortly after the museum opened....it does show the extra aerial mount on the side of the turret, mentioned earlier in the thread. Today only the welds remain.

Another picture shows one of the periscope covers laying on the front of the tank....sadly, those have disappeared a long time ago.
