Or, decreasing in size from base to chief. Oddly enough, the Decision does not describe the layout of the flag, only the position of the coat of arms in three official flags ratios. Also, according to the Decision the initials above the shield should be golden, but in practice, it seems that they are used mainly in green. It may be that there is some other act determining the COA and the flag, possibly the Statute. Anyway, I have assumbed the most natural from the text of the Decision, and that is the white cloth, but I am aware that this is mighhtily streched.
Some further evidence is needed.
Only the green shade is prescribed in the Decision as KS 53 K, by I am not aware what clasification that would be. Regarding the flag, the description there is all but perfect. The shield is on sides bordered golden. In red field on golden base there is a silver two-floor roundel, with open passage through its first floor with rised porticulis of three vertical bars. The middle of the wall above the entrance contains a right-angeled slanted line, both right and left above it there is an embrasure.
