Having made a similar double bow Windsor chair recently, I won’t test the bonhomie with needless repetition other than to mention one small departure.
Decorative beads are to be found on Windsor chairs from their inception though occurrences are relatively few. Employed mainly around the outer edge of back bows (fig. 1), they were also, less commonly used round the periphery of seats.
I cut a 3/16″ bead around the outer edge of the back bow with a scratch stock prior to fitting it to the arm.
