Swedish Three Crowns Military Helmet, 1921. CAMC Collection 31. 1 hat box.
This collection contains one Swedish military M21-18 helmet. The M21-18 helmet was introduced in 1921 as the second version of the M21 helmet. The first version, the M21-16 had a wider brim. M21-18 helmets can be identified by the three crowns emblem decals on the both the left and right sides, and the metal badge on the front. The three crowns badge on this helmet has been painted, but originally matched the color of the rest of the helmet. A similar version was introduced in 1926, known as the M26, which removed the three crowns emblems. A superior helmet was introduced in 1937 which was issued during World War II, though some M21 helmets were worn. There is writing inside this helmet: 528 23/38 Björn PÅLKEM
