The Sviatoslav of Kiev kit seems to be irrelevant here. The figure is the Viking holding a spear that appears in the middle picture in the PM catalogue reproduced above. But that figure had a base with steps without a cross, whereas the kit on sale contains the cross and a base with no steps, i.e. the base from the Viking with an axe kit. As far as I can read, the base also has an inscription –aire, which is consistent with the name of the manufacture, Poste Militaire. So, what we have here is the Viking with a spear and the base from the Viking with an axe. It is hard to say who mixed these two kits, either the previous seller or may be even the manufacturer. Both PM Viking kits are in fact the same figure, but with different weapon and bases. I should say I have never seen the Viking with a spear before, so this may be in fact a rare PM kit.
