Once I had decided on the construction method, I could crack on with the repetition.  This view shows all four fixed windows in place with the beading also secured.

The first of the windows with a sliding section has also been constructed and glued in place.  Only the fixed half of the top section is in place as the actual sliding window will be fitted behind it in it's own grooves. Note only two glass cuts for a full window and six!!! for a window with a slider.

The right angles are providing some weight while the glue for bottom section of glass sets.
