A little more to show.
The padded headrest and 'leather' cockpit coaming have been painted, along with the Vickers gun, and the Squadron markings and code letters applied. The fuselage underside 'ribs' have also been simulated, as if showing through the clear-doped fabric.
Photo evidence from 1918 shows that the code letters were mostly fairly crudely applied, and this has been replicated by hand-painting the letters and tail stripes, the letters being done freehand.
The rudder has also been painted white, to help minimise any 'show through' when the striped decals are applied.
I hope to post some more tomorrow, meanwhile thanks again for your continued interest.
