Help with Tool ID please

Pulled some things from an old tool chest.
Only marked with “Australia”
Aluminum. Three different graduations (red, green and aluminum) on the sliding piece in the middle. Spring mech catches the slots on the center piece.
Any ideas?

[paranoid56]

almost looks like a go nogo gauge. are the ends different sizes?

 

[scubadoober]

What are the measurements between graduations?

Left handed nut scratcher.

Very similar to a wheel marking tool used for woodworking.

Are the rod ends solid or tapped/threaded?

I was thinking the same thing, but I've never seen one like that.
Maybe for a specific application.

That's my guess as well.

Probably is. A lot of our gauging is part/feature specific.

Having not heard of a go nogo gauge before some google work, I would have to agree, especially with the green and red ends.

The ends are different sizes and shapes.

I have a woodwork marking gauge. Not quite the same beast

Ends are solid and not threaded.


Marking.
