I have an embarrassing number of metal miniatures, nearly all released in the period 1994 to 2004. They include Guard, Sisters of Battle and a few Grey Knights. The collection of models is intended to represent the forces available to an Inquisitor.
From White Dwarf 280 (2003):
The Grey Knights were sculpted by Aly Morrison, while the terminators were done by Jes Goodwin.
Why the Grey Knights (who are supposed to be 7 foot tall) are the same size as a human (see Tallarn figure below) while the terminator (the same 7 foot tall space marine in bulkier armour) is 25% taller is not clear.
YouTube so to start I am base coating the primed models with Leadbelcher and Rhinox Hide on the bases.
