I am in the middle of a shop clean-out and I am removing rust and refurbishing things as I go. I found some of these. I am pretty sure that this first set are for using taps. As in almost positive.

So that is all fine and dandy until we get to this set, that I also assume are tap wrenches.
Image Two: Special tap wrenches?

Specifically, the two on the left. Notice that they have this extra piece in the handle. That bit can sit in the center, the left, or to the right. Remember that I took these apart to remove rust and to clean them. This is what I found inside.
Of course, I wanted the part closest to the camera to be in focus. There are "grooves" in there. You see the bit that is in focus further away? That part has a bit that sticks out. The part that sticks up is flat on side and sloped on the other.

Here is a larger picture of the disassembled part after cleaning.

After I took it apart, I was able to guess at the purpose. Image two shows that there is a part that can move to the left, center, or the right. As this is rotated, it rotates the bit that sticks up so that the flat side / ramp side will rotate from left, to forward, to right. When this is pointing in one direction (say right), you can spin the bottom portion in one direction but not the other. If I switch it to the left, then I can spin this in the other direction. As it travels in the direction it can spin, the grove moves up the ramp (or more accurately, it pushes the pin up) and can free-wheel. The other direction hits the flat face. if I pull that bar straight forward then it hits the sides of the pin and it cannot free-wheel in either direction.
So my guess is that these are Tap wrenches that have a ratchet action. Never seen anything like it. Did I mention that my Grandfather was a tool and die maker.
That brings us to this odd thing. This image shows how I found it.

Those two holes drilled into the side, those are threaded, if a hole is drilled through the top. Are you ready for my odd guess? My guess is that I can stick a rod (square or round) into the hole in the top. I can then use screws, which are not included (sadly), to secure this in place. Then, the two round metal pits can be used to clamp something onto the end; for example, a buffing wheel or similar. I spent time thinking about this, but it is the best guess that I have.
Is this a die wrench? The square opening is smaller than any die wrench I have ever seen.

If you spin the green part of the handle on one of the sides, this opens / closes the ball. It does not make sense as a die wrench because it is just too small. Also, you cannot push a square rod through this because the handle goes all the way through. I am stymied on this one. I cannot build a good argument for anything useful that this might do.
