Rotating decoration on gallows f42v

[Wladimir D]

In my opinion, the presence of additional loops (the absence of a loop in the red circle) carries the meaning (not just decoration).
On the gallows of rice 1, 2, 3 in the blue squares are 3 identical monograms.
On 4, 5, 6 in the green squares there are also 3 identical monograms, with one of the loops replaced by an angle.
