i just came back from japan and i can confirm this is the set that they had in Akiba. I asked them about it since i noticed it missing when i went there and they stated they moved it to the new store.
They also moved a lot of the super rare items too as it was almost depressing on how many of the museum pieces were gone. I had to ask them if they had money trouble and were forced to sell but they all got moved there.
