Hi Greg...

Wonderful shots...very nice....

I posted this before somewhere at sometime but just a refresh post...

The Consolidated Canso was a fabulous aircraft, not the best but not the worse either...

The PBY5A was an amphibian...wonderful aircraft that is still in operation today.
The "Blisters" which you show on your pictures gave the aircraft a several Knot speed advantage over the Canso which used "Dutch Doors" or a door faired over the fuselage.
The Canso equipped with either was loaded at the dock or airport through these doors...no mean feat sometimes when loading aluminum boats, motors, passengers etc.
Like the Douglas DC3 everything was man handled, no rollers and nothing was easy and had to be secured to the aircraft.
This took time, patience and skill by the Ground Crew and Loudmaster who had to check the load and then rechecked by the Captain...along with the First Officer.
The Canso had a control column which had two wheels connected by a single bar/arm which contained switches amongst other things.
