The only thing that's stopping this thread from being marked solved is not having an ID for #5 so does anyone know who it is?
Here are a couple more pics if it helps anyone to solve the puzzle...
I see a lot of Russian text in association with these pics which doesn't mean anything to me so I wonder if it is just an unknown amateur cos it looks like it might be.
Also worth pointing out that pic #5 is now pic #4 given that #3 was removed due to being a fake of someone.
