Blenheim Nose
The two panels on the nose are metal. On some of the earlier production models the one directly in front of the instrument panel was glass but the pilots view through this was blocked by the panel so it was deleted and replaced by metal. Later the pilots windscreen was made to slide down giving a direct vision panel, when this was slid down a small windscreen would pop up to deflect the airflow from the cockpit. Its quite a complicated system and we are are not going to try and duplicate it, so the nose will revert to the earlier layout.
