I just got in an order of some Dogs of War Galloper Guns.  I won two off of ebay.  I am slowly building all the parts for this army.  In case anyone doesn't follow Col. Gravis, The Galloper Guns will be used for Lascannon chassis.  They are currently sitting in a Simple Green bath for some paint stripping.  I will post pictures once they are cleaned and I have assembled a prototype Lascannon.
