It may already be gone. If there are two small empty holes (one of which has the threaded portion of the hub underneath), then the screw wasn't reinstalled when the drum was removed previously.

Chances are it's just rusted on or there's a rust ridge preventing it from sliding over the shoes. I have about a 3 pound plastic hammer I hit them with to knock them loose. What's that in metric, about 1.2kg? If they break loose from the hub but still won't pull all the way off, you'll probably need to remove the console and loosen the parking brake cable to get enough play to remove the drums.
