Any idea?

No idea.

Where did you find it?
What type of metal is it?
What are the dimensions?

Your answer is in the details.

looks like half of an EMT coupling

Main bearing insert for an engine!

I thought main or rod bearing insert as well at first, but why 4 holes for something small ? And those bolt holes are small. But then again, that channel on the inside does look like an oil channel As ANTIQUARIAN said, we need more info.

looks like a main bearing insert to me.

I found it on a farm in Metro west Boston area that dates to the 1760. The edges are iron(there's rust there)and the rivets also but the band looks to be brass or bronze maybe.
I am likely wrong about this but the first thing that popped into my mind when I dug it was hand cuffs or irons ( hand or leg).

The U>S> nickel is there for relative size.

Could be.

From the picture of the outside, it looks like the Four holes are counter sunk which I get the impression would be for screws rather than bolts

Boom nailed it

 

[Reanm8er]

The holes could be for locating pins. This would be the insert for the cap and not the block side. The block side would have the
oil hole in the groove. I think locating or counter rotational pins. I suppose it could have been held fast with screws but the
back side seems to be countersunk. Yes the shell is steel but the wear surface definitely looks like Babbitt. One of a number
of alloys of tin, lead or zinc.

Thank you brothers!

:In the early 50's we referred to certain Chevrolet models as "Babbit slingers." They did not pump oil under pressure to the bearings. There were troughs in the correct places and scoops on the moving parts scooped up oil.

 

[HCW]

Thank you all. I had "no idea".

 

[Reanm8er]

Yeah piegrande, we called em "Dippers" because the rod caps had little scoops on them to
sling the oil up into the engine!
