Artifact History:	Built by the Albina Engine and Machinery Works, Portland, OR. Assigned to the Asiatic-Pacific theater. Served at Leyte landings, assault and occupation of Okinawa Gunto, and the Navy occupation service (Asia) until Nov. 1945. Was damaged in a collision at Iwo Jima with LSM-207 on Feb 24, 1945. Was the "White" beach control vessel at Hagushi beach in April 1945.

Artifact Condition:	Ship is in excellent condition. Although stripped of it's armament, it is largely still intact. No apparent major damage to the hull or superstructure. Propellers and shafts are present, as are most handrails forward. Some cabling on top aft of the bridge, but has very minimal loose debris. Numbers are visible on bow.

Additional Information:	Sold April 14, 1948 at Pearl Harbor, HI. Ship was converted to a Patrol Control Craft (PCC) in Aug 45', but hull number was not changed. It was not reverted back after the war as many PCC's were. PCC's were used for Amphibious landing operations. Extra personnel and communications equipment were added. Depth charges were removed to accommodate this.
