I had to research this and couldn't find a single photo of it with "01" on the tail. According to the Soviet Transports data files on this website it wore this serial from Aug 93 to Jul 96. After that it wore UAF-63957 for about 5 months and then became just 63957. In Feb 2003 it changed again to UR-63957 and then reverted back to 63957 in Sep 2012. I should also point out that some databases incorrectly give the version as AK-3.
