Thanks David
It should look better with the roof on
If you like double curvature roofs, there is no lack of them. The modeler is very much left out in the open, in what regards the assembly method. There are no tabs or formers. I glued some of the parts on thin paper and cut it to materialize tabs that allow proper links to the remaining parts. You can check that on the first picture. If the parts are correctly aligned, they fit perfectly, despite the roof’s odd shapes. A good point for the kit designer!
