Set 4 (AM): Riflemen, hats

Riflemen with m/23 uniforms and m/23 hats. The m/23 hat was the official hat from 1923 until 1937, but it was still used during ww2. It had the same colour as the uniform.
The m/23 hat was very similar to the m/ä och m/26 hats. The m/ä (model older) hat was dark blue and was the offical hat from the 19th century to 1910 when it was replaced by the m/10 hat. The m/26 hat was used by the Landstormen (home guard militia) and was grey.

Set 3 (AJ): Riflemen, helmets

 

Riflemen with m/23 uniforms and m/26 helmets. The helmet was originally grey but were later repainted green-brown-grey.
The m/26 helmets are very similar to the m/21 (high) helmets. The m/21 has a crest which the m/26 didn't. There were to different, but similar, helmets called m/21, one was called high and the other low because of the helmet's dome.

Set 2 (AH): Riflemen, hat

Riflemen with m/23 uniforms and m/10 hats. It was first used in 1910 and was still in use during ww2.
The hat was inspired by Charles XII and his Caroleans (Karoliner in Swedish). I suppose that the soldiers was supposed to think back to the "great olden days" and be more courageous.
