This is what the end of a short 6" Univac leader looks like:

Apologies for the poor quality, but even with the naked eye, it's hard
to see that the leader end is "looped" I might be able to enhance this
a bit with some image finagling, if anyone's interested.
The other end is cut in 45 degree traditional splice.
