Mini Square?

[TerryEastTexas]

This is what appears to be a tiny square. The head is 1" and the shaft is 2". It has eighth inch marks along the shaft. It is a solid piece of brass. Any help is appreciated.

Perhaps part of a small Vernier caliper?

My thoughts exactly. You are missing the body of th4e calipers. I have a couple of them in my toolbox, different shaped heads, but same slide assembly.

Wow! Looks like yall nailed it, so to say. Thank you.

What in the world would you use a 2” caliper for?

Looks like part of the ruler may have been broken off. Seeing full tool now make better sense.

I think it was used to get ahold of the edge of the work piece. Like the angel piece on the end of a tape measure.

A Google search revealed that folding rulers were invented by Anton Ullrich in 1851 and are called carpenters rulers. Made of wood, boxwood, ivory, bone, metal and man-made materials.

WoW
To have survived all those years.
I'd guess late 1800's.

we always referred to those as engineer's ruler. It's pretty old.
