This set uses the yellow-tan (officially "Gold") variant of the "Hunter Dungeon B" artwork, and consists of a recolour of the Hunter Dungeon 3 set. It forms seven pieces of an eight-piece set of the artwork.
Only the bracers of the same artwork and colour are missing. Luckily it doesn't matter for transmog, since they'd be hidden anyway!
But if they existed they'd look like Brassards de la chasse, but with a dark brown top band and a dark blue-black central band like the gloves have.
Head: Aeonus, Black Morass--normal and heroic.
Shoulders: Bourbierreux, The Slave Pens--heroic.
Chest: Chasseur d'époques, Old Hillsbrad--heroic.
Waist: Omor l'Intouché, Hellfire Ramparts--heroic.
Legs: Roi-serre Ikiss, Sethekk Halls--normal and heroic.
Feet: Zereketh le Délié, Arcatraz--normal and heroic.
Hands: Chef de guerre Kargath Lamepoing, Shattered Halls--normal and heroic.
For a hunter, I find that this weapon, "L'Espingole" suits the set quite well! Looks to be like it was designed to match it.
