The principal weapon was the spear, which the majority of the figures are carrying.
The spears are 32mm in length, which is 2.3 metres and historically perfectly correct, while they are very nicely done, with both the point and the butt-spike.
By the later 5th century the cuirass had disappeared entirely in an effort to further lighten the load of the soldier, although the latter seems to have returned later still.
All this means these men are only suitable for the first few years of the 5th century, perhaps the first quarter century (given that Sparta was a highly conservative society and was very slow to change or abandon traditional costume).
All have fixed cheek-pieces, and none have cut-outs for the ears, nor the completely closed face, which again fits exactly in our suggested period.
