1502 Strange... If the thing were a splice clamp to join 2 cables, the
lips on the sliding piece are on the wrong side. Perhaps it is used to
separate a pair of cables, with one cable resting on the chevron groove
and the other in the slot in the screw. But... this doesn't account for
the shape of the top of the slider and bottom of the larger piece, which
resemble a cable splice clamp.


Good eye, in the first photo the nut is on upside down, but it's shown
correctly in the second picture. Apparently I wasn't paying very close
attention when I shot the photos.


1505 I'm having trouble visualizing this. The first two pictures seem to
be of the same side, with the point of view moved a little bit down and
right.

Yes

The third picture seems to be of the bottom.

Correct, though the top and bottom look the same.

Is there something going on on the back?

The back looks the same as the front. A simple description of it would be
that it's a sphere with a ring around it, with four of the vertical parts as
seen in the first two photos.

I'll make a completely wild guess... A golf-ball vulcanizing mold.

It's not a mold of any type.
