Need to help IDing recent creek find 3" round metal object

[HISTORYHUNTER3013]

Found this the other day in a local creek, It's 3" round, taper on the sides, about 5/8 inch thick and may have had a hole through the center at one time.
open for suggestions.

Thanks, John

Reminds me of one of those trucker's steering knobs. They are still used on tractors a lot today.

Might be a flange to hold a shaft.

Weight off of a slide-hammer maybe .. or a clapper out of a large bell ?

Looks like bottom of steel fence post from old home or grave yard

What is the hole filled with? Is there any sign of threads or spline teeth?
It kind of looks like a bead roller for sheet metal work.

Looks like there is decorative work around the beveled area.
