First pic here: work so far on fin and rudder. I'm a little dubious about the fit as per the instruction sheet, but I'm sure it'll all be okay in the end...
A minor note: you can just see a small black dot at the top/front of the fin. They often don't bother to mould anything there, on the Triplane and other contemporary types, but I've noticed from photos that rather than running through the edge of the fin, support wires often went through a small extension of the vertical post, so I've placed a tiny piece there to suit.
Also (sadly) the fin will indeed be green, because this is supposed to represent Collishaw's earlier machine. I gather he only painted the fin black on his two gun machine.
Second: the underside at an early stage. Yes, I've had a go at filling some very noticeable sink holes! I'm generally quite forgiving of sink marks, but in this case... wow.
And now I look at it again, and despite all the double checking I did, I'm wondering again (this being a single gun machine) if I actually removed the correct shell case chute... Yes, I did
