What is this cap badge?

Hi,
Can anyone give me details on this cap badge? I found one earlier in another thread listed as a "Bartszowe" Battalions - pre 1918 badge. But I can find no web reference to "Bartszowe". I think it may be associated with the second brigade? It seems very uncommon....I would like more details about it's use.
Thanks in advance!!!

Well, I have found a photo of the badge in use...on the cap of Hieromin Przepilinski, a legion officer in the second brigade.

Well, I have finally found a reference to the Drużyny Bartoszowe (Bartosz Brigades). This was one of the prewar paramilitary rifle clubs that joined other clubs to form the Legion in 1914.
Here is another image of the badge...
