View of the rows of shingles comprising the inner wall of the nozzle extension.

Picture 7 of 7.

This is a somewhat unusual view, as it is taken from forward looking aft. Most people are more familiar with the view from the perspective of aft looking forward.

The yellow rectangle has a rubber pad on its backside (i.e., the side which engages with the nozzle extension). This sometimes leaves a mark on the interior of the nozzle extension.
