The only airframe that I could prove to be converted to the long range configuration is L/N914. this airframe was converted in 12/2001 . The airframe was scrapped after a cargo fire inside a hangar at BKK

The other way around : ANA modified two 747-481 aircraft to the 481D configuration (shortend wing + removal of the winglets), to produce a short haul aircraft in 2003 at the former Boeing Military Airplanes facility (Wichita).
However the fuselage was AFAIK not fully upgraded to the real 744D's specification.
Both aircraft are already sold and converted again by Bedek, now as a 747-481BDSF(again with wingextension and winglets) before the cycle count became to high.
Aircraft involved :
1133 28282 747-481 R2716 RT756 ANA
1142 28283 747-481 R2724 RT757 ANA

Operating a twin over the ocean, you're always one engine failure from a total emergency.
