Woodruff keys are often used on tapered shafts where it is easier to machine than setting the work at and angle to mill the slot and the taper takes the load and key just acts to locate the item on the shaft such a timing gears/pulleys.
I seem to remember that the Austin Seven had this arrangement on its halfshafts.
Either type of key seat can be machined on a vertical mill but the straight key way would perhaps be more difficult on a horizontal mill.
Woodruff keys and cutters are readily made in the amateur workshop.
I assume that model makers would aim for authenticity of key type.
PS Excellent illustration, Ignatz!
