Looks like a drum trap, except I do not remember seeing one that is threaded.
Drum traps were often used in tubs/ showers and floor drains.
Google Drum Trap for more.

Looks like the type of drum trap often used with claw-foot tubs. The clean-out opening would be in the floor above the trap.

Dead ringer for the drum traps in my rental property, circa 1951.
