Relics from German battleships sunk off Orkney are among a lifetime collection of antiques going under the hammer.
A ship's clock is among the collection being auctioned
A ship's clock and other items were retrieved from the fleet sunk at Scapa Flow after World War I in 1919.
The array of auction items was salvaged from the wrecks and eventually collected by the late Norris Wood at his home on the island.
The collection is now expected to sell for thousands of pounds at Bonhams in Edinburgh on Friday.
Mr Wood turned his home overlooking Scapa Flow into a private museum in 1961 and it became a popular Orkney attraction.
However, relatives recently decided the museum could not continue operating and are selling off the contents.
A Bonhams spokesperson said: "The points of interest are the diversity of the collection, its links with Orkney and with the sea."
A range of Georgian and Victorian furniture and antique clocks, pocket watches, pottery and porcelain are also included.
