A search for the Russian long range flight piloted by Levanevsky was contracted by the Soviet government with Sir Hubert Wilkins in 1937. Two seasons of search flights failed to locate any sign of the aircraft.

A small number of covers were canceled at the request of the search crew at various post offices during the period November 16, 1937 and March 18, 1938.

At the beginning of World War II, Jan Mayen Island (in the Greenland Sea) was known as Island X, a location of strategic value as a meteorological station. All mail was canceled with the Norwegian Navy ship cancellation. Early in the 1950's the meteorological station was upgraded and the staff enlarged so that they were serviced by regular supply boats that carried mail to Tromso for servicing. A new and distinctive cancellation was used on later mail.

The radiogram was sent through the Leningrad Post Office on June 20, 1941 regarding formation of a Kara Sea Exploration Expedition . . .
