I bought a Case fixed blade knife and I think it might be a fake?

It looks like no case knife I can find online. It measures almost 15″ long and the blade is 10″ long, 11/2 ” wide, 1/4″ thick and is straight. It is marked CASE XX only. The handle appears to be stag, but I am not sure now. I think I can still get my money back if it is fake. Any help would be greatly appreciated.
