Naval Covers

This section lists active links to the pages displaying covers associated with the ship. There should be a separate set of pages for each name of the ship (for example, Bushnell AG-32 / Sumner AGS-5 are different names for the same ship so there should be one set of pages for Bushnell and one set for Sumner). Covers should be presented in chronological order (or as best as can be determined).

Since a ship may have many covers, they may be split among many pages so it doesn't take forever for the pages to load. Each page link should be accompanied by a date range for covers on that page.

This section lists examples of the postmarks used by the ship. There should be a separate set of postmarks for each name and/or commissioning period. Within each set, the postmarks should be listed in order of their classification type. If more than one postmark has the same classification, then they should be further sorted by date of earliest known usage.

A postmark should not be included unless accompanied by a close-up image and/or an image of a cover showing that postmark. Date ranges MUST be based ONLY ON COVERS IN THE MUSEUM and are expected to change as more covers are added.
>>> If you have a better example for any of the postmarks, please feel free to replace the existing example.

Other Information

NAMESAKE - Sumner Increase Kimball, Sc.D. (September 2, 1834 – June 20, 1923)
     Kimball was the organizer of the United States Life-Saving Service and the General Superintendent of the Life-Saving Service from 1878-1915. Originally a lawyer and a legislative administrator, Kimball spent his life creating and leading the Life-Saving Service, one of the predecessor services that eventually became the US Coast Guard, transforming it from an uneven collection of facilities round the US coastline into a coherent and well-trained organization.
      Kimball was born in Lebanon, Maine, raised in Sanford, Maine, graduated from Bowdoin in 1855, and admitted to the bar in 1858. He was elected to the Maine Legislature in 1859.
      He became a clerk in the United States Treasury Department in 1862, and was placed in charge of the Revenue Marine Bureau there in 1871. When the Life-Saving Bureau was organized in 1878 he was appointed its head. Under his direction, the Life-Saving Service was extended to the Pacific Coast and the Great Lakes.
      Kimball also served in several other positions at the Treasury Department (acting Register, acting Comptroller, acting Solicitor). He was the author of Organization and Methods of the United States Life-Saving Service (1889) and Joshua James-Life Saver (1909).

Three ships have been named in his honor - USCGC Kimball WMEC-143, SS Sumner I. Kimball (Liberty ship) and USCGC Kimball WMSL-756.

The ships sponsor is Kay Webber Cochran, wife of Senator Thad Cochran, Republican-Mississippi.
