That looks like a copy to me.
The top plate is the right size and shape for a Leica III (or II, for that matter) - which would mean the rangefinder would have to match it - which would mean the focus mechanism would have to be exactly where and what it's supposed to be in a Leica II or III - which suggests this is a Leica. The lens I have greater doubt about, because of the stylized f -- none of my Elmars have that. But it's not a Fed lens (the most Elmar-like Russian copy) - the aperture selector is the right width for an Elmar.
There is the slight possibility the top plate is from an old Nicca, which seems to be the closest Leica III clone -- but I don't know if they made any Leica II copies.
This camera is pretty gaudy, though....
