Bell 206 Chin Perspex
In the 1980's Bell/Agusta modified the design of the 206's chin perspex resulting in a new 'convexed' shaping. Intriguingly (well for me at least) was the fact that the port-side piece displayed more pronounced 'blistering' than the starboard (pilot's) side. Any illumination in response to this prime piece of trivia?
