Larry,
Is the kit 72nd? If so, here is a decal sheet with what you need.
"1:72 Mi-24D/V/P/VM, Mi-25 Hind (11 options)
* Mi-24D black 328, Sandanista Air Force, Nicaragua, 1987. Red-brown (FS 30219) with leaf green camouflage (34079) over light blue (35526).
This set is from Begemot (that's 'Behemoth' in English) a new Russian decal maker who have produced sheets in 1:72 for the 'Helix' and 'Hind'. The description is based on emailed scans, so no definite comment on quality can yet be offered, although they look good so far. There is evidence of slight colour mis-alignment on both sheets, but nothing serious. Information about availability should follow in a few weeks time. "
This info is according to Heli-kit news http://www.5chr.freeserve.co.uk/hkn161.htm
Linden Hill is also supposed to release another set of markings for the Hind from Bush Wars sometime this month. No idea what is on it but set one includes a lot of interesting schemes. http://www.lindenhillimports.com/lhd48006.htm Set 2 is number LHD 72012.
I have seen other sets with these markings but not sure if they were old Microscale, Hi-Models or someone elses.
