So to the cockpit
The first thing to bear in mind is that almost none of this is going to show when the fuselage is joined up.
The second is that there are all sorts of unidentified rods of various lengths that put together or keep apart the cockpit frame and its contents. These all must be measured to establish which goes where (definitely not a Tamiya kit!).
Thirdly it seems to be very easy to construct this with a barber shop twist in it. Careful line-up is essential.
This pic shows most of the contents in place and unpainted. In the end I used my own plastic rod to join the two frames together. The area forward of the compass and aft of the radios is not visible later. Nor for that matter is the compass (luckily!!).
Two more pics show the positions of the parts and how they are mounted.
