I am currently working on a Grey Knights Land Speeder for my Warhammer 40K Daemonhunters’ army.
I do realise that it is not in the Codex and there is not a lot of fluff to support such a model, however I do think it will look cool.
Using the Land Speeder which came with the original boxed set, purity symbols from ForgeWorld and a book and skull from the Inquisitor range.
The crew lower halves needed to be cut back as they were rounded and when the Grey Knight (metal models) are cut in half they will need a flat surface to stick to.
The Land Speeder weapon systems were “donated” to my Ork army to become a Loota unit.
The entire model was then sprayed black. The base colour is Boltgun metal.
