The Rhinos are the Mk1 kits from Chapterhouse Studios. Personally I prefer the new MK1 kit from Forge World myself, but I don’t think they were even out back then for Charles to use.
But the Contemptor Pattern Dreadnoughts were, and they look great!
The rest of the models are mixes of Games Workshop kits, Scibor, and Maxi-mini figures respectively. Regardless of the mix of brands the army looks great, and has a solid cohesive theme throughout!
Enjoy the picture spread below, he even labeled each model for us! FOR THE EMPEROR!!! - Enjoy MBG
