The photos of Old Whitey 'Mount Empress' AM/AOS in OrchidWiz shows a deep yellow throat, but that doesn't mean much. Yours could yellow with age, or it could be a different cultivar.
Old Whitey is the parent of 68 hybrids though, so unless your old tag gives you a pretty clear idea, I wouldn't bet the farm on the ID.
I think you are right Ray. I don't know what I was doing wrong, maybe it was late last night I was trying to find pics of it, but now I found a bunch. Not too sure this one is correct.
Its an old collection, and one of the plants I hadn't repotted. The owner/boss, handed it to me and said.. "can you make out this tag?" of which was in 4 pieces, and not complete.
