Frank - I very much doubt it or it would have been snapped up my a museum etc.
Besides it looks to be in too good a condition to be original.
Drew - I took another, closer look at the photos and I think you're right - there does seem to be a faint outline of and inspection window, as illustrated by in the resin set sheets.
I'll go with that as well - thanks.
The rear cockpit decking panel was tricky to do, but then I didn't expect it would be easy.
Once all of the flash and the mounting block was cut away, I sanded the bottom edges and rear face.
The 'Wingnut Wings' kit fuselage was temporarily joined with elastic bands and the shoulder at the rear sanded away as it stopped the resin decking panel from dropping down.
I soon found out that, no surprise, the resin decking panel was not wide enough to sit correctly on the fuselage.
So I cut the panel down the centre and rejoined them, but with a 1.0 mm thick plastic card insert.
Carefully sanded to the decking profile.
The front decking panel - that's another story!!
