I don't know what these are for

[Tony (Michigan)]

The quarter is just for size.
The large square thing has four short legs. Don't know what is was for.

The buckle thingy has a sliding middle bar. Any idea what it was for?

Found on the farm I live on with the V3i.

Someone on another board said the square thing could have been a sewer drain or shower drain.

Square metal base could be a porch post base to keep the wood up out of moisture. Peace Roy

The square holed thing Looks a lot like old drain cover.

Buckle thingy - strap / sling adjuster?

 

[timwied]

Yep, harness strap adjuster.

Buckle thingy - strap / sling adjuster?

The silver round thing is a quarter.

 

[Agseeker]

The silver round thing is not silver; it's a copper/nickel clad quarter. lol

What ever it is it looks new. The Quarter. Square drain? Maybe.

The disc with the hole looks like a wick adjuster.
and the "button" next to it looks like a trouser fly button.
Richntr is correct the Buckle thingie is a strap adjuster.
and finally the square thing looks like a floor drain cover.
Those are my 2 cents worth...
Now what do I win??

I think it's likely, being on a farm, that the buckle is a strap adjuster from overalls. The square thing has a small chance of being an old type timber connector (very small chance).

The brass disk on the right is a Winchester shotgun shell. The center fire piece in the center fell out. Found a lot of those. Clean off the face of it and you will see a headstamp that probably reads "W.R.A.Co.", a "12" or "10" ga, and something like "RIVAL" or "LEADER"
