Hi Andy and Gilles!
These parts are 100% identifyable as Me109E
The Armour - That shape and style is only Me109 E (not F or G)
The Oval Wing Hatch - Specific to Me109 E as the were design was changed in the F
The part of large skin (indicated as the gear door) shows wing ribs that are 100% the desgn type of the Me109E.
So 100% Me109E, and not F or G.
Mike
