Sylvanus Sawyer of Fitchburg, Massachusetts, patented this style of projectile on November 13, 1855, United States patent #13,799. The patent date "Nov. 13, 1855" is stamped on the slightly concave lead base. Note the nice pattern of lands and grooves on the lead sabot from the 3.67-inch Sawyer rifled cannon. This specimen was found at Port Hudson, as have been most examples of this type. |
