Measuring Device ?

[dlane]

Hi all , I've Ben picking a cl add for a while now and this is about the last of the unknown to me items.
It has graduations to 36"the slider has its own graduations and rides in dove tails, no name on it , it is well made.
First thought is for a lathe bed travel, won't work on my SB 10L , any practical uses for it
Thanks

A really accurate yard stick? Dunno, never seen one of those before. Big inside caliper?

Vernier scale.
Is that metric?
No manufacture marks?

No manufacturers name on it , not metric , at first I thought I could adapt it to my lathe saddle, I guess I could make brackets for ends and clamp slider to lathe saddle , it would be hard to see tho.

Is it inches or somthing else.

I don't know what it is, but it's for measuring thousands of an inch. The base scale is set in half tenths, or 50 .001s. In the top picture it reads 21.224.

Edit: typo.

It looks like a big inside caliper that would have come in handy when I was decking one of the jon boats I've remodeled.

I say it is reading 22.424

21.224. You read the scale to the left of the zero on the vernier.

I'd use it to read out the knee position on my mill. It has about 2' of travel but no dial.
