Current state of the work:

Cockpit pieces.
I wasn't able to retrieve any info about the cockpit outfit, so I followed other fellow modelers build...
On the left you can see 2 versions of the panel behind the pilot: one has X shaped struts on the opening (I have seen a panel like that in another build and I scratchbuilt it) and the other (provided by the Kit) is a solid one. I don't know which one I will use.
On the right you see two IPs the thin one is photoetched and the other is from the sprues. I decided to use the former.
The aluminum panel was made by me to separate the engine compartment (the other side is painted as wood) from the cockpit.

Seat with PE seatbelts (cushion made by me using FIMO paste)

Instrument Panel: I glued a white piece of plasticard on the back with some instrument decals, but they got ruined when sliding towards their location. I made many tries and in the end I didn't have any more left so I must be happy with them.
I dropped some "Synthaglass Liquid glass" by Dr. Toffano (Italian producer of great paints and varnishes) on the instruments.

Here you can see the interiors of the cockpit, the V shaped struts are from my fantasy.
I tried to enhance the struts profile with a Van Dyke Brown colored pencil smudged with water.
I will add some more detail (gas pump, compass and throttle) before closing it.
The engine compartment has been painted using a 50/50 mix of Tamiya Flat Aluminum XF-16 and Tamiya dark sea gray XF-54 to give it a less shiny finish. I need to work more on this...
This is the full pilot pit. The control stick, the curved feet tracks (don't know their correct name) and the feet holder are made by me.
I added a piece of plasticard under the seat to raise it a bit, it looked too low!
Ciao
