    Is the bottom arrow fixed solid or does it spin?

    Looks like some kind of manual auger

    Acme thread on that... I wonder what that fitting on the bottom might have matched with? I'll bet the thingy (anyone have a better word) in the middle there fit into some kind of socket -- possibly a socket with a clamp which bolted over it -- and it was used to adjust the opening of something, like a window... or a damper...

    That thread reminds me of post jacks used in a basement for sagging beams. The pitch of thread looks like it could apply a lot of push or pull to something.
    Was there a coal burner in there?
    Maybe something for the CI grates?

    Depending on what the attachment on the lower end is made of, it reminds me of a valve seat dresser like my grandfather used in his shop in the mid 1960's. I repaired many valve seats then with a tool that looks just like this one.

    A step above the rap on the knuckles with a ruler?
    It looks like something to deal with boiler tube problems to me.—NBC

    Whatever it is it is very well constructed so it did not come from the Harbor Freight catalog

    I'm thinking a puller of some kind - the threaded crossbar would sit in a groove on the outside, and the end piece would lock into whatever was being pulled.
