Unique items

I have come across a list of a few items that I found to be interesting and have only seen them in a few houses. I'm curious to find if these still exist or are just rare in and of themselves:

1. Model Griffon Tower
2. Fallen Iksar Skull - Collection Quest
   
3. an Iksar Ship in a bottle - Quested
   
4. Goblin Stewpot - Quested
   
5. Twin Candle wall sconce
6. Drednever Scryer Sphere
7. Sathir's Uplift
8. The wards of kelkarn
9. Tranquil Scrying Pool - Collection Quest
   
10. Incense Holder - Collection Quest
    
11. Tunarian Potted tree - Collection Quest
    

I hope to find some info on these and update this, moreso for myself but if anybody else happens to come across them as well.
