This is the Games Workshop, Space Wolves Iron Priest 53-19

This multi-part plastic kit contains all the components necessary to assemble one Iron Priest, implacable armoured battlesmith of the Space Wolves. He comes armed with a helfrost pistol and tempest hammer - ordinarily used for forging and smelting, but also pretty handy to wield in a fight - and includes a servo arm. This model is supplied with a Citadel 32mm Round base.
