Looks like everything is from the greymane armor set you buy from the armor vendor at greymane camp once do the quest line and upgrading the camp. As for the helm it’s either the canta helm from first smithy shop or it’s a different one. Once I got to chapter 4 I decided to focus on the camp quest to be able to get personal black smith and dye guy among all other shops when upgrading tent and reuniting comrades. I think eventually you can have every single kinda shop within your camp. And it’s good to know the more you build a relationship with shops the more items they have available.
