I can't find the white Rejuvenation Winged Vessel in the "vestibule next to the great hall"

[Tuxedo Kamen]

I am looking at the walkthrough on here and I am stuck in this one part with how to find a winged vessel. This is what it says:

Back at the vestibule next to the Great Hall: In a room beyond the left (north) doorway, you'll find a white Rejuvenation Winged Vessel; its only purpose is to recharge exhausted Vessels; if you pick it up, it does not appear in your Inventory because it is NOT one of the ten you need to finish the game. But if you need it, this is what you do: Go through that doorway, turn left, go around the corner, run straight ahead to the next corner. This hall now goes all the way around a blue-silver central room packed with skulls. There are four skull cages inside this room; shoot the skulls through the bars. When you're sure they're all dead, go to the one open cage, and push on the large beetle engraving on the back wall; this opens a cage on the other side of the room.

Go to that cage, and do the same thing to open the third cage. Open the last cage the same way, then when you push on the fourth beetle engraving, you can get to the Winged Vessel in the center of the room."

I don't see any blue silver central room with cages in it. And the only beetle engraving I see is the doorway to the dining room which I am not supposed to be in yet. Are there any screenshots or videos or anything to show what the person who wrote this guide is talking about? I spent about 10 minutes wandering around and can't find squat!

I think he/she is talking about the 1997 version of Killing Time, this 2024 remaster has simplify the Great Hall structure, and changed Winged Vessels location.
