AHH, A youngster are you?
Those Visions are the very first stab at caging that Vision produced in the early 1990's. I, personally, prefer them over the granite color but the masses spoke and granite won out.
I have 14 of the cages that you see in the photo. I also have 2 of the white arboreal cages, before they produced the granite arboreal that has the horrible shroudlike thing that wastes space and prevents you from mounting a radient heat panel on the inside roof.
Just goes to show what the masses can do if they get together.......
Glad you like them! I do as well.

Best regards,
Jeff
