SOLVED!
I'm about to buy a Soviet leader Russian doll set, and it goes in order: Gorbachev, Brezhnev, Hrutchev, Stalin, Lenin. I'm guessing therefore the Hrutchev is just an alternative spelling for Khrushchev, but on Khrushchev's wiki it doesn't mention this alternative spelling, and when googling Hrutchev all results are in Russian, and google translate isn't much help.
Thanks, hope this is a quick yes/no answer!
Edit: So there is this Wiki, which looks like Khrushchev, but it's another alternative spelling! https://fi.wikipedia.org/wiki/Nikita_Hru%C5%A1t%C5%A1ov
Remember that Russian is written in Cyrillic alphabet and transliterations may vary. As already said, "kh" is just the usual transliteration of the 'hard h' (i.e. Cyrillic 'x') to English. Other languages that have the same sound, but expressed by a different letter, will used it eventually. e.g. In Spanish, Khruschev is transliterated as Jrushchov.
The language of the manufacturer of the dolls (Finnish?) probably transliterates the word with an 'h'.
