Tap or die - I can never remember which is which -- the one for threading the inside.

Indeed it is a tap!

Specifically, a 3/4-14 NPT tap.

Cool. I'm looking for one, now.

 

[snowbear]

OK. I don't see a reveal photo so you'll have to take my word when I finally say what it is.

Corrugated fence?

The bottom of an old sink? The underneath part, I think.

 

[snowbear]

Nope.

A clock escapement.

 

[snowbear]

Not a clock, anything.

It is an object, that is common in urban and suburban areas; not so much in rural areas.

An old shed

[snowbear]

Nope, but you get a free guess!

 

[Borad]

Dumpster?

 

[snowbear]

Not a dumpster.
