This engine cowling is from a Hawker Siddeley HS125-700B business jet.
Built in 1979, it saw service initially with a Swiss operator, before wearing a number of UK registrations.  It ultimately ended its days on the Aruban register and was parted out around 2009.  
We acquired the engine cowling and have polished it to a mirror finish, restoring its white gloss finish to the base and vents.  Fitted with an 8mm toughened glass, 1m diameter top.
