Skyrim PS4 - Item received again?

I stupidly sold a Dragon Priest mask some time ago in Skyrim. The Morokei. Now I need it for a kind of "unofficial quest". Repurchase does not seem to go, because no dealer has the mask more. I do not have a score from the time, so; is there anyway a way to get to the mask? Can I somehow fight Morokei again, or is there a hidden chest where the game keeps all the items you sell?

Usually the dealer has the still

There's a room where all items are available, but only by cheat code on the PC

then there's still new game or seek who has it

Nope that's gone Sorry…

Typical rookie mistake… If the dealer does not have it anymore, that's the mask. Maybe there helps a mod, otherwise you have had bad luck.
