This could possibly be an ID plate off of an old power pole.

 

[SeekerProB]

Drill bit gage or wire gage

Any photos for comparison?

As SeekerProB said it could be a gauge of some sort...looks live partial circles on the left side.

I would say the Lid to a drill bit Box.

Has nothing to do with drill bits.

 

[Ozark Redneck]

Drill bit gage or wire gage

I would say Seeker hit the ID right on

I think it has to do with measuring water flow in second-feet.

It is a calculation chart or multiplier chart for something.

Read the numbers across from left to right.

The first column is X1, the second column is X2, the third is X3, the fourth is X4.

125 250 375 500
130 260 390 520
140 280 420 560

I can’t really tell much about the left edge. Are there more numbers?

Some info/context of where found (near or in a river, near a road or highway, near a home, etc., etc.) might help with the identification.
