Plumbing Help

No access panel to the plumbing on the back side of that wall? My house is from the same era and has a drum trap. Easy to clean out if you have access to it, but impossible if you try to snake through the tub. That is where I would start.

ETA, I couldn't get my drain ring to move either. You can start with one of those bendy plastic sticks with spikes on them to clear the hair though. Does that drain take an immediate 90 degree turn?

Yes, I can get to the plumbing in the back; I haven't noticed a trap, but will look.

Drum trap is likely. A camera would help. Usb cameras are cheap.

The part that is missing is called the overflow plate. It usually connects to a rod that has a plunger in the line with that type of drain. The plate would have had some type of toggle on it

There was a lock ring to hold the overflow pipe. The plate screwed into the lock ring. Both the lock ring and plate are gone. I haven't seen anything like it at the hardware store. There wasn't a toggle and the drain was stopped with an old type pull plunger.

Is the Drum trap designed to be opened?

I can take a picture of the backside plumbing tonight.
