Six photographs of a cannonball which are also marked 81/70, 81/71, /81/72/, 81/73, 81.74 and 81/74a. They were taken by Walter K. Schroder. and are so stamped on the back. There are three letters. The first letter is dated Jan. 21, 1981 and is from Walter K. Schroder to the Smithsonian Institution. National Museum of Natural History. In it he says the cannonball was found in late 1980 during excavation operating on the west side of Jamestown. In a letter of March 3, 1981 from Craddock R. Goins, Curator, Division of Military History to Walter K. Schroder he says "the cannonball is an example of an English 24 or 32 pounder cannon ball that could be from the Revolutionary or era of 1812 period. The mark you observed is probably the British broad arrow used to designate Government property." The third letter, dated March 10, 1981, is from Walter Schroder to Mary Miner re the letter from the Smithsonian of March 3. Cannot determine what the 81/71-81/74a records are for. Not found in objects or photos - needs more searching.
