Bulgarian Military Merit Cross - 1915

This appears to me to be either of the following awards:
Soldier Cross "For Bravery" 1st class
Awarded to low rank soldiers for exceptional actions in the face of remarkable danger. There are 5 variations of this award:
The first was issued until 1915 and is dated 1879 on the reverse (as are all variations) and undated on the front with 7 symbols;
The second variation, which was issued from 1915 to 1918 is dated 1915 on the obverse and has Bulgaria written in Cyrillic;
The third variation is also dated 1915 on the obverse and has Bulgaria written in Cyrillic, with the exception of the letter I which is in Latin;
The fourth variation is dated 1941;
The fifth variation which was created in 1945 is undated, but has a star and two lines on the obverse.
The award is issues in 4 classes:
The first class of this award differs only from the second class by the way of the first class having an additional ribbon sewn across the ribbon suspension.
or Military Cross "For Bravery" 2nd Class.
Awarded to low rank soldiers for exceptional actions in the face of remarkable danger. The second class of this award differs only from the first class by the way of the first class having an additional ribbon sewn across the ribbon suspension.

I have no real knowledge of Bulgarian awards and hope to be corrected
