Not sure how much you care about earlier expansion quests but I'll just add them here as I come across them.

• The Plume of Alystros - Dragonblight - Item is called 'Skytalon Molts'
• Mystery of the Infinite - Dragonblight - 'Hourglass of Eternity'
• Mystery of the Infinite, Redux - Dragonblight - 'Hourglass of Eternity'
• That Which Creates Can Also Destroy - Dragonblight - 'Seeds of Nature's Wrath' (it did come up for Turgid and Overseer)

Right, button didn't show up for these ones except for mentioned exceptions.

Did the items not show up with EQB?
