Pre-WW2 Italian M33 Combat Helmet (Airforce)

A non-messed with, early production Italian M33 steel combat helmet with all original/correct internal components.
This service used helmet has the type 1 dome vents with 2 prong internal folds and early type brass hollow rivets used to attach the grey/green leather chinstraps (one section missing) indicating manufacture between 1934 and 1939.
What is most interesting is the different layers of paint finishes, starting with the factory applied grey then the depot applied Airforce blue/grey with frontal insignia, this being a gold coloured four bladed propeller with intermediate radial lines within typical Romanesque wreath.
The top layer may be field applied during the Spanish civil war of 1936-39 when most of these early helmets were being worn by Italian units supporting Franco or possibly a WW2/ post-war application, very difficult to say with M33 helmets.
The size 60 liner is in good order and has the correct parallel bar stitching on the seam, no metal eyelets on the tongues which again is correct on earlier liners, orange colour underfelt padding visible (yellow post-war).
An appealing early 'been there' M33 helmet.
