As for the rest/shelf. Fred was old school, where the arrow rest on the knuckle, because longbows were first made without a rest, then a tab was added and eventually some started to cut into the bow a small shelf.
Being old school, it was much easier to continue to shoot that way, why change? But the public liked the elevated rest, because they didn't like having the finger cut by rough quills on the feather. Many did not bother to grind the feather smooth on the shaft. The early Bear bows 1954-56 came out with slightly elevated rests. People like it for shooting. It became popular, but not necessarily better. Longbow shoots still shoot with the lower rest. It is like pointing your finger at the target, more natural than with an elevated rest.
Shooting like Fred did was like point your finger at the spot you wanted to hit. I like it better and shot that way for years.
