Warhammer 40,000 – Salamanders on bikes. Yes they seem to look a bit space wolfish but this is another one of those salvage jobs. My client got a good deal on some models and wants them to look like the rest of his force. So green space wolf looking bikers will be one of the more savage clans from Nocturne.
From the stuff that was pre-assembled they appear to have been part of a command squad. The storm shields on the side of the bikes give that away. I'm guessing the chainfist guy was supposed to be the apothecary.
