PPK-02: Tantei Jinguji Saburo: Hai to Diamond Original Sound Tracks + α

[MiLO]

Well, I think PPK-02 is not as much of an appropriate catalog number for this one as TCI-1189. The thing is none of the actual album's artwork/booklet/obi mentions PPK-02. The disc itself has TCI-1189. I own this album in full and can confirm. Also here's Surugaya's link.
The Obi has advertisement for <PPK-01> KIND OF BLUE, so I assume that PPK-02 was in a similar manner on an Obi to one of other Tantei Jinguji Saburo albums.
By the way KIND OF BLUE currently has catalog number JING0001-2, and I don't think that's correct either, Surugaya has it under TTCD-1180, I think that's what on the disc. Can someone who owns Kind of Blue soundtrack confirm it?
