This is a later edition of Keibunsha's All Monsters Phantom Encyclopedia than the one that I bought from Japan.
As normal, it contains 600 pages of summaries of special effects and monster shows.
Since it was published in December 1983; a couple of years after X Bomber was made and televised in Japan, I suspect that it only features the usual 2-page glossary about X Bomber that we see in photos below.
I doubt that X Bomber features in the few colour pages at the start of the book, since those pages seemed to cover only shows that had just been released.
