Bill,
I'm sure glad both you and Steve are building this ship since I know I'll be getting ideas from both of you.
One thing that puzzles the heck out of me is that on page 6 of my Trumpeter Dreadnought 1915 instructions, parts F20 and F21 (the hinged gratings on the forward funnel) are shown as having to be attached. According to my John Roberts book, The Battleship Dreadnought on pp. 200 and 201 those gratings are definitely NOT part of the 1915 refit. I'll be leaving them off. Very strange .
I hope I'll be able to catch any other minor differences that might be mistakes in the instructions but, even if there are some more and I don't catch them, the world will not come to an end.
Mike
