So an improtant question for me is, did the Swedes have any good looking helmets? Yes, in a matter of fact they did have some good ones. Between 1916 and 1926 there were 4 different models, confusingly two of them are both called m/21.
|fm/16, with removeble comb|
|Svea Livgarde (?) soldier in old m/ä uniform and m/21 (flat) helmet|
The next model is the m/21 (flat). The reason it was called flat was because the dome was flatter than the other m/21 helmet. The brim was different from the earlier test model, but still wide compared to later models.
M/26 was very similar to the m/21 (high) but without a comb.
Next model was start being used in 1937, so I will not cover it here. The m/21 and m/26 was used until the end of ww2.
