According to the law, this is not an army flag. Be h the height of one stripe, the height of the shield is equal to 1,3 x h and the length equal to h. The shield is of XIXc French style. The bottom of the shield is on the middle of the white stripe. The 1929 eagle has no chains.
Drawings are in the law.
The offset towards the hoist was somewhat more in the case of the jack in the first pattern and considerably less in the case of the second pattern. According to National Geographics 1917, the war ensign was added the second arms, but without the green half-stripe. I'll report when I come to something of interest. The jacks were, similarly with German jacks as we learned from Norm Martin's excelent series, as a rule smaller in size then ensigns, possibly with different proportions, but I don't have refference to back up this claim. I believe it was Norm again who told me that.
