Anyone seen this puzzle on Ebay?

I haven't seen one before, but found a reference to it at:

Any idea what it is worth?

Now Cubologist has a two-link puzzle for sale:

How do you take a Missing Link apart without breaking it?

If you pull up one of the silver end stickers, you will see that the puzzle is held together by a single plastic shaft that has a snap feature on it's one end for fast assembly. (I know this because I am missing both silver stickers on mine.) All you have to do to disassemble the puzzle is pinch the snap features together and the shaft can be removed. I'm not sure, but I think you could easily replace the plastic shaft with a longer or shorter metal bolt and add or remove parts from another Missing Link puzzle with a locknut to produce a "pocket" or "master" Missing Link. Then you could cover up your handiwork by returning the silver end stickers.

I would guess that both of these variations were modified, not manufactured. If, however, the silver stickers actually say "pocket" or "master", then I would become a believer that these were actual manufactured puzzles. Then again, the new Oddzon Rubik Revenges only say "Rubik's Cube" on their sticker; so who's to say for sure?

So, if you have 2 spare regular Missing Link puzzles, you could make 1 of each version.
