II period around 1945 - 1947
From the few photographs I have seen, I am of the opinion that in this period the ranks are moved to the collar of the uniform.
The stars remain at six-rayed for the military officers.
In some images it can be seen that the insignia of ranks are also present on the hat of the officers. Unfortunately I have not found images that depict the ranks of senior officers.
