brit propellors
My work was at Britannia's (1966 onwards). who inherited some of the Ex BOAC ones and to add to some of the comments, yes the round tips were made by De Havillands under licence,. Glad to hear the comments from people who actually worked on the beasts. As a reminder of that time I still have a torque bleed tube for the engine ,and special tool for setting up the prop microswitches in my retired toolbox.
