During WWI Standart was placed in drydock and refitted with new boilers. Very shortly after the refit she was in use as a hospital ship and I've seen pictures of her where the flag of the Red Cross is flying from the main mast; the flag defined as a protection symbol during the Geneva Convention of 1864.
After playing a short role during the revolution as basis for the revolutionairies and after the escape from Helsinki in April 1918 she was again shortly thereafter placed in drydock until Stalin in 1937 decided she would be converted to a minelayer. Most of her inventory had in the meantime been recovered from the vessel and this is the reason why at "relatively modest" prices items such as glassware and porcelain plates can be obtained at auctions. Part of the inventory from the private suites of Nicholas and Alexandra were transferred to Stalin's dacha at Kuntsevo.
In various museums relics from Standart have survived; I have personally had the keelplate from Standart (attached to the keel in 1893 by Alexander III) and various items from the bridge in my hands. My father has a serious collection of original drawings, paintings, photographs and other artefacts from Standart.
Just fantastic that the revolution has not been able to wipe out everything,
