It was properly called "zweiteiliger Stahlhelm" (two-piece steel helmet). In 1958 the helmet was made as a one-piece helmet and renamed Stahlhelm M1A1. The M1A1 came in three sizes: 66, 68, and 71. This helmet was used until 1981 when a modified version was released and renamed the Helm1A1. Modifications included a 3-point chin strap with the third point connecting at the nape, extra large sizes, and a further adjustable liner. The M1A1 Stahlhelm remained in service until 1992 when the Bundeswehr replaced it with a PASGT-derived kevlar helmet called the Gefechtshelm ("Combat helmet").
