The above photographs were shot at NAAS Shelton, Washington during World War Two. They are undated but were with a history of the base that stated that airship operations did not begin at the base until November 30, 1944 when a mooring mast and circle were completed. If these were shot on that day then this airship is ZNK-71 of Blimpron 33
The above series of photos is the airship K-29 performing what might be the first non-rigid landing on an aircraft carrier aboard CVE-18 Altamaha in February, 1944.
The above photos are of K-19 & PT Boats 17, Dec 1945 on the Potomac river.
