West Wind's Irish warband is, judging from the rest of their offerings, aimed at the early Dark Ages or Age of Arthur. Nonetheless, it is not too much of a stretch to use these for the era of Viking invasions in Ireland, especially in the ninth century.
Below, a group shot of all twenty. For a paint scheme, I stuck with a limited palette. The shields were all red and white and I worked on plenty of variations of Celtic crosses, some historical and some improvised in that style.
The rank troops are for spear or javelin (unsupplied) and come in four different poses. Hands will need to be drilled out in order to fit the weapon. Heads are separately cast, and there are 10 variations. Shields are separate as well (except for the musician).
There are also four unique figures in the set. Two are warriors with short swords, which are cast-on and not separate. For a SAGA warband, these can serve as your Curaidh.
The other two unique figures are a command character with a banner and a musician. The rough and improvised banner is the detail that most distinctly places these figures in the pre-Viking age. Using a separate staff and Viking-era banner is easy, but the metal-cast banner is nicely sculpted and unique among my collection. I went with it.
These are good figures but do require a bit of prep work. Drilling the spear holes is a plus for long term stability, but it is an extra task. Casting quality is good, but some cleanup of jagged areas is necessary. The neck pocket will also need to be opened up a bit on most of the figures in order to get the head to glue in properly. That is a small price to pay for having some customizeable options.
For SAGA, these twenty figures give you two points of warriors, a half a point of Hearthguard (Curaidhs) and a Warlord. One would need at least 12-20 more figures to get a complete six point warband out of this box, so this could best serve as an expansion to an existing army in that game.
