Just like i before e except after c this isn't correct in practice.
There were three different types of Rotol props found on CBAF built Mk V Spitfires.
Early style with blunt-spinner and narrow-root metal blades.
Intermediate variant with broad-root wooden blades and blunt spinner.
These were only found on the earliest aircraft up to early AD.. serial range.
The most common, long pointed spinner with broad-root blades. EN951 had this type.
de Havilland propellers had short pointed spinners.
Don't forget that EN951 had a yellow letter D painted under the nose.
