Strange markings but Fazakerley were still FTRing them for sale overseas and as they were withdrawn, for War Reserve stores. The Government were desperate to keep Fazakerley open but try as they could, the self imposed death wish was too great! ROF 6 was in fact Fazakerley but this is clearly 1965 and VERY late although they were still in limited UKicon military service until the later 60's A new type serial number too because they were allocated serial number blocks commencing VS and if a lost number, then a ZZ number and later a SA-- number.
