Hi chaps, Picked this up at Tankfest on Friday, was told it was a Panzer IV wheel cover. I didn't think it was, thought it was a Tiger or Panther underside maintenance hole cover so I bought it. Got home and see they had 5 bolts not 6, so I don't know what it is off of. Was told its WW2 and from Normandy. It measures 275mm diameter, 230mm bolt hole centre to centre, and about 30mm thick. So pretty beefy and not Brit or US given the metric dimensions. Can anyone identify it please? Many thanks!
