For those of you who are doing door handle related props, I just stumbled onto the actual door trim plate. It's from Weiser Locks (who are/were based in South Gate, CA - not too far from Disneyland) and looks to be the actual off the shelf trim piece imagineers may have used. I've compared it to the castings that I have and it looks spot on.
