One Primarch and bunch of Marauders

These are some new resin and metal minis found on eBay. Pretty expensive, to tell the truth, but interesting. Just want to share these pictures (not mine).

I bought this guy and he looks even better without his cloak. But is rather large - compare with the base (40 mm). Unfortunately, the head is cast with the body, but still quite easy to swap (resin), if needed. Which Primarch he might represent?

 These marauders are metal, but I have not seen them in person (too expensive to consider).
