My pershing is re-enacting euorpe WW II western front somewhere between normandy and the rhine.  I know the pershing came into the war late, where all was the pershing deployed in euorpe?

What is the domed framework on the right front fender for?  I have seen them in historical pix but nothing is inside the framework. 

I would post a pic but I seem to be too dumb to figure out how.  Even my 14 year old could not help me.

I will check in later, I must go to fire training now.
