This post-war update of the Model 1926 helmet features the final liner system, which replaced the previous three pad system with one resembling the American M1 helmet liner.

       
 

 
Swedish Model 1937/65 Steel Helmet

The Swedish Model 1937 helmet featured less of a rim than the previous model. It was updated in 1965 with a new liner system. Millions of these helmets were produced until the helmet was removed from service in the 1980s.
