A short time ago I traded for a green acrylic Klingon PADD that looked to be of a screen used type but didn’t match what I could see in the movie at the time. In the movie you can see an obvious hole in it that is in a different location than mine.
This is the one I have.
A sceen cap of the one floating with an obvious hole.
A cropped and exposure adjusted shot.
A recent UK auction sold one of these that also didn’t have the hole and was also broken.
They compared it to an earlier scene where it is just lifting from the table.
Now that I can take HD screen caps I think the one I have is that one on the table. It looks to have a hole in the same spot as mine. Although that could be artifact, the edges tend to have a highlight which shows in the above screen shot, and there is something there in the following screen shot but not in the area shown above.
The rest of the possible tells look OK to me but that could be wishful thinking.
