This Skitarri trooper was made from the arms, chest and sergeant-head of a cadian guardsman with the scope and pocket taken from the scout sprue and the addition of miliput (greenstuff will do) to sculpt the hood.
The barrel of the lasgun is a hull-lasgun from the Chimera sprue and the wire on the scope is guitar string.
Although the legs on this model are not from a GW product suitable alternatives from Bitzbox would be the cadian officer legs or the high elf archer legs
The purity seal is a forgeworld inquistorial one. As for the sholders, they were filled back to just cloth and the cog-pads made from plasticard, and glued in place last.
All other parts are available from Bitzbox!
