Your following and comments are really encouraging.
Thank you all.
In the meantime I prepared the side walls of the cockpit , with the additional pieces.
Here is the photo of the preparation
I already painted the whole thing but it was too late and I went to sleep without taking pictures.
Great adds. I'm concerned though that your instrumemt panel is not going to fit properly on the right half because of the placement of some of the parts there.
Yes Vic, from the picture I posted, Andy would be right, but the pieces were only provisionally placed before being painted. Once they were colored, I glued them trying to make it all work... I hope
