    Those inserts don't go with that tool holder. It appears you have right hand inserts with a left hand tool.

    There are both right and left hand inserts in the photo.

    Looks like it's for internal and or face threading.

    "back-face" threading?

    btw, the shim seems to indicate the first picture is the correct use.

    Hardplates is correct. Put the insert in the lower right of photo 1 in the pocket.

    Doesn't have to be a back-face. I run lots of left hand tools with M04. In my experience many if not most turning centers are more rigid when run M04.

    Is there a number stamped on the holder?

    That looks like a holder for "on edge" threading inserts that are held on with a special flat head screw. Like a TNMC-32V insert for an example.

    That's what I thought at first glance too, but the geometry would be like this, top face flat:
