The globe shows present-day St. Petersburg, Russia, as “Leningrad;” therefore, it was made after 1924. Further, it shows Constantinople rather than Istanbul, indicating a date of manufacture before 1930. In addition, it shows Northern Territory in Australia, rather than North Australia and Central Australia, indicating it was made before the 1927 geographic division and name change, or after 1931 when it was changed back to Northern Territory. The gores (maps on the globe’s surface) were printed by the British firm of G.W. Bacon, imported and manufactured into globes by the American firm Weber Costello, and sold by C.S. Hammond. The Weber Costello diamond-shaped cipher is printed above the cartouche.
