I know nothing about the RK but the other items are junk. Add that to the fact that he is asking 85 Euro and better judgement says that you should run away.
hmm yeah i read something about that the date is to far down and to close to the beading, and i suspected it was way too good to be true
The inner corners of the beading are rounded too, this is a famous fake type from my memory.
not what you want to buy.
