Hello!
In that case I can help you some more with it! I have re-built a model like that recently:
More on it here:

Well, those Hinds were delivered to Poland somwhere in the late seventies/early eighties, in three colour camouflage and they basically kept that camouflage into the 21th century, when they were reapinted solid green for missions in Iraq and Afghanistan. One thing to look for is the tail rotor warning text. Initially it read "опасно" - which is "Dangerous" in Russian. They flew like that for years, and then during major overhauls this insription was repainted to read "niebezpiecznie" - which also means "dangerous" but in Polish. That's why we know your paint scheme is a bit later - say 1990's - and so the photo of the pilots I posted earlier would fit just perfectly. Hope it helps - good luck with your build and have a nice day
