Hi Johan,
These crosses are the minefield, to be honest.
First of all, I've read about such types:
1. Cross for privates, 1st and 2nd class
2. Cross for officers, 1st and 2nd class
3. Cross for bravery/merit, also in two classes (with swords).
Ciphers of ppl awarded differs from source to source, something like 20 ppl / 1st class of cross for privates and around 100 with the 2nd. As for officers/bravery crosses, only few of them were ever given.
As far as I'm concerned, no one has ever shown neither 1st class of any type nor the 2nd class for bravery.
What disturbs me when looking at your pictures...following the description these crosses were NOT enameled.
1st class badges for privates were gilded and the 2nd class badges were silvered with gilded shield, while other two types were gilded with silvered wreaths.
Jani Tiainen once showed this cross which looks believable.
Whoever made enameled specimens, when and why--I have no idea.
One more from the internet. Translation: Bravery Cross of the Ingrian White Wall
