Light saber sculpts:
As mentioned, the Luke bespin figure comes with two different Saber sculpts. The first one was shown above and came on the first three figures I picked up. The second saber sculpt is documented here. I have put together a picture highlighting the differences. The Kenner / Lili Ledy Figure is on the left.
First off, and most noticeable, is the extra piece of moulding to the side of the saber.
Secondly, there is an extra piece of saber holster connecting it to the upper belt.
Finally, the saber itself is sculpted differently. One features four horizontal lines as opposed to three buttons on the other sculpt.
