__________ 1938 Westland Lysander 1

Canal in 1939, circles the Gebel-Mariam monument


What are these things (well) above the wheels?

How do you call the aerodynamically (*) shaped
features in which the wheels are nested?

(*) or at least one would hope so.

Also why do the wings have this double taper
(see next picture where it's more apparent)?

Thanks.
