we bought a 1932 home last year and notice when the bath water fills up to the overflow, it leaks to the dining room ceiling. I unscrewed the cover plate and find behind the tub:
1. A broken hardened runner gasket that is leaking
2. A very thin metal gasket after the rubber gasket
3. The brass drain down spout tube
4. The down spout has a left & right threaded lug where screws go that hold the thin metal gasket against the drain spout.
5. Theses screws are also threaded internally in order to take the screws that both pull the drain spout forward against the tub and also hold the chrome cover plate that goes on the outside of the tub and raises & lowers the drain stopper.
Overall it functions like all the overflow drains you see in store except for the 2 internally threaded screws and the think metal gasket which neither I or 3 different plumbing stores have ever seen before!
The problem is the repair. There isn't enough room to slip the standard beveled replacement rubber gasket between the tub and drain spout. At best there's 1/4" opening and there isn't a door to get to the tub. The repair must be done from inside the tub.
I took a short video which shows the structure, inner metal gasket and double threaded screws. Hopefully your website will allow the video upload. If it does you'll see the issues/problem instantly
Since the usual 3" diameter gasket is too thick, I found a 3" x 1/8" which I was able to slip in between the tub and drain down spout. Then I forced plumbers putty between
the tub > putty > 1/8" gasket > putty > drain spout
The thin metal gasket sits flush seated just inside the drain spout so doesn't seem to be an issue. I can't begin to figure out what it its tsp purpose is actually. It's diameter is larger than the tub overflow hole, so I can't remove it. Actually it's thin enough I probably could bend it over to then force it out the tub hole. I could cut it easily but if it turns out to be needed, I'd have destroyed it.
Another idea is: since the space around the drain spout is about 1/4" - I could sand the beveled soft drain washer so it's 1/4" around and then install it instead of the 1/8" hard rubber washer and putty. Because the beveled washer is softer, I'm thinking the putty wouldn't be needed.
But to conclude, I'm at a loss why I can't find our 1930's tub set online, or any pro plumbers who recognize ours. It's like it never existed! So odd.
The video is just a bit big to upload, so I uploaded to my server if allowed to do is at:

Thanks for any insight,
