Unidentified Messerschmitt data plate

Evening all…

This has us bamboozled over on the LEMB. We have very little background information.. other than the data plate below…

…which can be found on this item.

Other than I thought it looked like a spinner or cowling… does anybody have any ideas as to what the item is and the type it was fitted too?

Cheers
