Congratulations Matt, a nice M1915
Were you able to find out anything about the owner? Are there more information about the regiment? The name is hard to read, but it seems to be „Josef Groller“ or „Josef Graller“ or „Josef Grella“ or „Josef Gralla“. The last 2 names can be found in the „Verlustliste“ (Casualty list), but there are more than one. I hope you will be able to find out the owner at the time. Good luck
