My inspiration came from the Broodlord-model. I wanted the Lone Wolf to have his arms to the side, howling for the moon. The Wolf Guard box set should have what I need. Well, almost. All the chain fists and storm shields are left hand only. So I had to convert either a left hand shield or chain fist. I chose the latter. I couldn't find any picture of a good conversion, so I made my own, very simple one, from a power fist and the saw from a chain fist Not a smooth conversion, but good enough.
A little bit of green stuff later, and my Broodwolf came to life. Considering the amount of time I spent, and the result, I'm satisfied. The shoulder plates are not perfect, but a bit of paint should cover most of it. Also, the arms are maybe a bit to long. But, hey, Space Marines are not Homo Sapiens, so I don't care. Here's the final result:
Oh, and Merry Christmas!
