Out of all of my years collecting helmets, I have never seen these in the U.S from a retailer. These are rare helmets, as most were either sold to struggling African countries in the 1980s or were re-worked to the M75 configuration.
Patterned after the U.S M1 helmet, early M58 helmets had U.S liners in them! They also had a rear-seam on the rim just like U.S Helmets from the 1950s onward. These were the first models which were all Austrian made.
If you are a helmet collector, or know someone who is, this is a must-have for collectors.
