I have changed my plans and will not be doing a Space Wolves Pre - Heresy Army. Instead, I will be creating a pre-heresy Imperial Fists army. I have not given up on the Space Wolves that are my favorite army. But as their rules will not be updated for another year and a half I will not waste time making stuff that will likely be redundant in the next Codex.
Thus, onward to the Imperial Fists. During the Great Crusade the use of Dreadnoughts was limited due to their not being really that many mortally wounded heroes laying around to stick into dreadnoughts. For some reason you had to be really cool to be kept alive in an armoured hospital gurney.
Anyway, here is the start of what will be an Iron Clad Dreadnought for the Pre-Heresy Imperial Fists.
