Explanation for the use of Greek letters "χρω" to write "CRW" as confirmed by Riccardo Ferri: Standard transliteration of Greek letters "χ ρ" is "ch r" (here used for "cr"), while "ω" (transl. "ō") is only used for its optical resemblance to letter "w" due to no standard Greek letters with transliteration "w" being available.
The Media Records back catalogue and the digital release of "Hazley" list "CRW" as the official artist.
