Hi All: I was given a tool recently and as far as I can tell it is
called a center finder made in US by Mituyoyo.At least it says it's
made in the US but I can't imagine it would be with that brand name.
I found one on ebay exactly like the one I have.

I can't for the life of me figure out how this tool would be used or
where I can get any info on it. Is it used on a lathe? Any info on
this is greatly appreciated.
