Pertinent information summarized from the object file:
In 1897 the British Museum requested that some of the objects being reported in the press as having been found in Benin during the Punitive Expedition
be sent home for study. The Foreign office agreed and Sir Ralph Moor duly sent back a shipment of plaques some time in March or April. In a later list, Read (Charles Hercules Read (later Sir) was the keeper of the department of British and Medieval Antiquities) noted 305 plaques that he was able to select from, although there appears to be others at the foreign office as Read mentions plaques in officials offices...[t]he 305 plaques were displayed for 3 months at the museum from September 1897 and a report appeared in The Times. The British Museum were able to keep around 200 of the original plaques...[t]he remainder of the plaques all bore the large white numbers such as is on yours, as did the museum's collection. They are Foreign Office numbers, we call them Read's numbers, Bon Lushan called them Sir Ralph Moor numbers. Read gained permission to handle the sale of the remainder and duly offered various plaques to museums around England and Europe, the results were listed on a document called "Fate of the Benin Bronzes" which uses Foreign office numbers."
