I was thinking maybe you made a mistake about Nazarova being Russian recordholder. But then I discovered that Olga Vladykina (Mrs Bryzgina) - 48.27 in 1985 Canberra World Cup for USSR - is actually attributed these days as being from Ukraine.

My humble apology for ever doubting you PJ:)

Yes, i was wondering the same thing.
