I bought this manual on the Spanish version of ebay, and it arrived today !. The interesting thing to note is that the cover states CPC 464 but the manual’s title stated CPC 472.
The CPC472 came with some bizarre aspects, too. Reading 464 on the cover, but 472 on the bookneck. And, claiming that the 72K RAM would be required because of using the ROM of the CPC664 (whilst, the real CPC664 has only 64K RAM).
You can see photos of it here.
