Starboard siren RO9 from the HMS Ark Royal, built at the end of the 2nd world war, to replace the old Ark Royal, sunk in the med. The Harrier Jump Jet started life on the HMS Ark Royal, and this is the ship on which Rowland Humble, the owner of the world's largest steam whistle collection served. The “new” Ark Royal has just gone for scrap. This particular siren was once featured on Blue Peter.
Smith and Dennis 5 chime air horn. Bespoke made for the American market, for use on a diesel tug. This is a very unique horn – there is no other in the world with this chord.
