History
Battery Trevor was designed to protect both the Straight of Juan De Fuca and the Admiralty Inlet to Puget Sound.

Originally built with two, 3" M1903 rifles mounted on M1903 barbette pedestal carriages. The original guns were removed 16 Nov 1933 and shipped to Fort Mills, P.I. The carriages were removed and scrapped in FY 1942 during World War II.



Current Status
Battery Trevor has two 3" guns with barbette pedestal carriages currently on display that were obtained in the 1960s from Battery Flake, Fort Wint, Subic Bay, Philippines. Both breech blocks are missing because they were thrown into the Pacific Ocean to prevent enemy use when Fort Wint was abandoned at the beginning of World War II. Both guns and carriages show battle damage.

The battery was clean and dry when visited. The storeroom was locked but both magazines were open.
