Bavarian Pilot Shoulder wings? What are these tiny crosses?

[Ravenft]

Greetings Gentlemen!

I have my first piece of WWI Aviation history (at least I hope I do!) A shoulder board wing from what I believe is a Bavarian unit.

Question! What do these small crosses on the bottom mean? Are they a type of makers mark or quality control mark? Also I noticed that one of the wings seems bent out of shape but I can find NO stress marks showing that it was bent in that direction. Was this a common occurrence that the wings were not symmetrical?

All the best,

Ravs
