This is NOS, a full unopened bottle of Castrol Hydraulic System Mineral Oil Plus 500ml bottle complete with the RARE filler tube. This is for the Jaguar XJ6 AND XJ12 from 1987-1994. It is a classic JAGUAR part with the paper top cover describing what it is used for in different languages. This would be a great addition to the JAGUAR showroom or when showing at car shows.
