OK, I'm with you now. Is the the mark you long for? I don't have a photo of a real mark only this drawing.
Nonetheless, about the ring's marks. The second mark is supposed to show a right looking kokoshnik identifying the assay office. The third mark tries to show the coat of arms for Warsaw (a double headed eagle) but in that case the second mark should carry a cipher (a dot) behind the kokshnik's neck (1913-1917). It should look like this mark:
Does the second mark look like the picture above (it looks more like a man with a beard) and where is the dot? In general the whole outlook of it is "odd"? That is why I am a bit suspicious.
By the way, it would be interesting to know what is the exact diameter in mm of the second mark.
