Man,that is beautiful! But do my eyes see something strange with the port prop blades;namely,the two lower closest camera.Are they extreme aerofoils,or maybe the front part of a hollow blade design is missing! I'm only guessing here. I would like to know...anybody..
I believe those are Hamilton Standard Hydromatic (adjustable pitch) propellers, shown in the feathered position. The concave surface is actually the back side of the prop blades.
