cpc 464 Spanish version .. serial number

[retro_4_ever]

just got hold of this cpc in a job lob.. just realized that it is spanish ? i think ..
serial number : 544-8Z16570 .... what does the "Z" mean i thought that digit 4&5 where the year of production .. and strange keys... whats the 'n' symbol with a worm above it
was thinking of changing the rom and the different keys .. but its in amazing condition .. doesn't even look like it was ever used .. apart from a couple of scratches on the rear .. edge connectors are mint, tape deck looks unused.. and it arrived in an original cardboard box
the box has a serial number on it but that does not match the cpc (544-8x15655)
