I'm leaning toward an original due to some minor corrosions i see on the markers and the edge of the subdials. Also, the original subdials has a shinier lacquer finish which yours seem to have on the updated picture.
With the extra pictures, to me, it appears to be original for reasons others have mentioned above.
Also regarding the vertical brushing I have found, depending on the lighting angle, it can sometimes appear more pronounced even on the original dials.
A sharper picture of the bottom of the dial would help clarify the shape of the 'A'.
