The words “Administrator of General Services” are substituted for “Federal Works Administrator” because of section 103(a) of the Federal Property and Administrative Services Act of 1949 (ch. 288, 63 Stat. 380), which is restated as section 303(c) [303(b)] of the revised title. The words “United States Postal Service” are substituted for “Postmaster General” because of section 6(o) of the Postal Reorganization Act (Public Law 91–375, 84 Stat. 783). The words “real, personal, or other” are omitted as unnecessary.
