Vintage Russian Made Binocular Microscope? M 2-2 N330870

I've no means of dating this wonderful Russian made binocular microscope and without a Cyrillic keyboard can't copy the model number (photo of the card is in the gallery). Russian lens were rightly acknowledged as being world class. I was tempted to say that this was a 1960s item but the collar around the bottom of the stand looks like brown bakelite to me. Comes with its original lockable box and key.
