Many thanks to all of you for your supportive and generous comments, they are highly appreciated!
I continued the work on the fuselage and adjusted the cockpit opening to the shape which seems about right to my eye. I am glad I invested the effort into the interior details, as eventually a lot will remain visible.


I also started working on the upper side of the fuselage.

As the Camel featured small inspection windows on the leading edges, I want to represent them on my model too.
I used paper templates to find the right position on the wings:

Afterwards I carved the holes with this tool which Sergey Mertens made for me. Many thanks for that, a great jig!

The next step was black paint and inserting 0,6 mm diameter circles made of aluminium sheet.

The glass was added by using photopolymeric glue, Will see what it will look like once sanded and polished.

Cheers
