As Jacques said - the first one is not even a fake, it's a fantasy camera like so many other FED conversions on ebay. I guess there is a market for especially "soviet looking" cameras that have KGB, GPU, or communist logos engraved on them.
The black magnetic FED has been around for a while, I put it in the wiki some time ago.

As the black paint could be applied at any time there is no way to verify it's originality.
About the magnetic features I'll write a seperate topic, might be interesting but it is definately not limited to this camera. I my opinion thhis is a normal FED1'd' that has been painted black (with some skill I have to admit) and that has a FED1'e' base plate.
