Today in Furniture Catalogue
addon I found redguard oven as well with materials needed to craft this item. It's marked as "Services" so it should work as provisioning station. But in Crown Store it doesn't exist, also I never saw blueprint of it or already crafted item in guild stores.
This is how this oven looks like (screenshot taken in Craglorn tavern):
It also can be seen on Hunding's Palatial Hall loading screen. Can someone confirm that this item exist in game and can be crafted? I really want it for my new house
