I've just received a sunshade for my Mk 1 Big Nikko which was made by Mick Tromans. It is an excellent fit & the paint work fully matches the scope. My thanks to Mick for making this for me. I would fully recommend him to anyone wanting a sunshade for a Mk 1 (or Mk 2) Big Nikko scope. He is a member of this forum as "SEDGLEY Ti" For information, the sunshade was 100mm long and cost £30 including postage.
