Are you in a regular room where you're trying to find the list of hidden objects? If so...is it maybe the Servant's Quarters' room...and I'm totally going off of memory for this...but I think it's on the rim of the golden horn of the phonograph on the right edge of the screen. It's a bottle opener just like the one used in the puzzle that giggy described above...the one you said you completed to get in the room you're in with the bed. Hope it helps...

Yea, I just played in that room a bit ago and it is on the bottom rim of that golden horn of the phonograph...so, hopefully you'll find it...
