This helmet shell could be an actual USA M1 or clone like the M53 made in The Netherlands.
In the rim we can see the inscription RUCO EP.
In The Netherlands there is still is a company called Ruco Metaal.
Site: www.ruco-metaal.nl
But they were not the makers of these helmets.
I received information that RUCO was not a production company but rather a trading organisation.
They gathered and refurbished helmets for export.
A new stainless steel rim would be installed with inscription RUCO or RUCO EP.
In most cases used USA liners would be installed into the shells.
I found information on the internet the letters EP are telling us this helmet was made for Peru, and
if only RUCO the helmet might have gon to Indonesia.
These helmets are from the sixties and seventies.
If someone knows more about RUCO please let me known.
