So, what to do with a surplus of pretty nice helmets? Export!
Stocks of this helmet were unloaded to the Greek military and designated the M.34-39.
The shell is nearly identical to the Italian helm save for the lack of those three distinctive ventilation washers.
Sold sans liner to the Greeks, the helmets were repainted by the Hellenic forces and used during the conflict between Italy and Greece in 1940. I can only imagine that the close similarity between the helmets of the opposing forces must have caused some battlefield confusion.
