Vologases III or Mithradates IV or something else? [解決]

Hello,

I got this (in my opinion) beautiful persian coin. I first identified it as Mithridates IV, but it does not seem exactly correct, so i immediately thought maybe Vologases III was the one, but it was not that either. Maybe it is a variation of one of the two or an other coin. Links to Mithridates and Vologases: N#43481 N#74157

Thanks in advance,

Diameter as specified in both pages of the coins.

Help is greatly appreciated as always :)).

I think, this is exactly  Mithridates IV without any doubts, if we  follow Seelwood: long ponted beard, earing visible, three pendants,  and Aramaic upper  line  (rev) . 

Thanks so much. After all 7 years ago i got it correct..
