Unfortunately, I don't have a bow armature file.
What I did was to get a drawing pad, pencil and a ruler and measured up the INSIDE of the taped together bow section. Using those measurements, I drew a diagram of a box, about the size of an old audio cassette. Then I added another, smaller section to that, altering the first diagram. This piece is the neck. To ensure you get the correct dimensions, you'll need to assemble the main hull to the stern, and slide the relevant pieces onto it(cue lots of fiddling), before butting your(still) taped bow section against the front fuel module. Look down, through the girderwork and make the relevant measurements.
Then pop-off to your local lasercutter and have the pieces cut..
When drawing your diagram, put marks on it for the screws and wires to pass through. You WILL end up using screws to hold it on, as superglue on it's own is not enough!
Another very important thing to note: The hull armature is wrong in one section. When the drawing was made, no consideration was given to assembly- the glazing beneath the upper spine, when assembled, sticks out wider than the interior of the front fuel module section. Not the top piece, but both the diagonals. After you assemble the armature, the pieces will need trimmed, as the front fuel module is impossible to fit otherwise.
All good fun....NOT!
For paint-Uk bronze- Chuck it on-the plastic drinks it up!So don't worry about missing anywhere....
Once that's done- drybrushing the brass on is sooo quck and easy- it's really enjoyable and you'll be amazed at the results you get, very quickly. Good luck, and keep on posting buddy!
). If you look at the pipework on the upperspine section of your provided picture, you'll see it's a green hue. That''s because the original filming model was constructed from brazed together brass. When cooled, it goes an orangey pink colour, before rapidly corroding to various shades of green. You can see this, if you look for pictures online. They are out there. There are also various pictures of the unpainted model in this thread.
