It's difficult to be sure if the leg was black, my friend @lis. Also, if you look inside the round bay opening, the shade looks tad lighter than the surrounding black, meaning it would have been left the previous gray? Might this be the case with the leg?
Anyway, I believe that you have to go with your own interpretation, whichever of the above it will be it will be deeply researched and look anyway possible, because, who is going to prove you wrong?
