I have seen this NKS on sale, the seller claims it is (of course) original and gold grade. For once the pictures are quite detailed, I have some doubts about authenticity when I look at the catch (especially the base of the catch). Maybe a staegemeir fake? or I get too paranoid…
Furthermore, I’m not sure about the grade. I would say it is gold grade with a part of the finish absorbed by the metal but couldn’t it be a bronze grade under artificial light?
Well, I’m sceptical with it and would like to know your opinions.

thank you by advance for your comments.

regards,

Pierre
