Not sure where to start

Makes me think of something automotive like a chrome shift know cap or maybe the and cap of a lug nut that was sheared off... motor dressing accessory.

Does the milled out side have threads onsite of it? Does it look like it is a complete piece or like it could have broken off of something?

3 ounces is the weight of 17 nickels. Does it weigh that much?

Is it magnetic? Is it attracted by a magnet?

Do you remember what its VDI was?

looks like a chair foot

Thanks for the feedback

It’s not magnetic or attracted by a magnet
Inside of the hole is threaded
Looks like one complete piece
@Arthurevans your right I’m way off with the weight. I got a digital scale and it’s .807 oz.

@cadmaster I’m liking the chair foot guess.

Possibly the button of a push button switch like an old starter button in the dashboard of a car from the late forties. It would have had a separate bezel and screw on to the actual contact switch. Turn on the key and push to start.

Pointer?

Is it the end of a pointer that teachers used to use on a telescopic rod?
