I accidentally sold and forgot about my dragonpriest mask from the dungeon forelhost. It was the one with +70 stamina, and I need it back to be able to complete the dragon priest mask thing. I play on PC so is there a command code to get thus mask back or a way to do the dungeon again because it won't seem to reset either. Thanks guys =)

I had the same thing happen when I sold them without knowing the little quest it goes with it.

I did this though to recover my 'lost' one:

player.additem xxxxxx 1

EXAMPLE: player.additem 00061cc1 1

Here is the code list:
