I have no skill in model extraction or anything like that, so screenshots and where to find the items need to be sufficient.
So with no further explanation I open for you the weapon lockers of the 3rd Bitterstone Thunderers to show you some beauties.
ATTENTION:
The Item pictures you see here which are not Screenshots are from the Game Client. That means that these Items may currently not be available as Items in the game.
