The authorization for the sale of 90 surplus P-51 Mustang fighter planes to the Government of Sweden was given […] due to the fact that these planes were needed in part to replace and furnish spare parts for 50 P-51’s sold to the Swedish Government in July 1945, […]. Therefore, the sale may properly be viewed as the completion of an earlier sale. […] In making the 1945 sale and the present authorization, the Government of the United States recognized the fact that Sweden rendered
valuable services to the United States during the war in returning American air crews forced down in that country and in other wartime services.
