Yeah their are the legitimate ones you find through most dealers, and through Oktava's store online of course. But there are also some other ones, there is a complicated mess involving Oktava and another guy/company that was licensed to manufacture and sell them but he made them differently - a lot of people have said those sound better than the original, actual Oktava 012's. If you do a search on google about it I'm sure you can find a few websites with some information regarding the whole deal. Guitar Center was actually selling the licensed ones a long time ago. I'm pretty certain that these days it's harder to find the licensed ones anyway though - the original Oktava 12's will be easier to find.
