Need help! Old rifle found in archives

Hello everyone, I have found a old rifle wrapped up in a flag in a leather bag.
All the information I could find on it was "captured hardware" that is it, no ammunition type/size or whom it was captured from. The only information I can see on it is the following;

Mannlincher-Schonder 1930 System
Y:1903/14

The Y:1903/14 had a shield above it on top of the receiver.

Any help on its history, calibre ( it looks like a 6.5mm )

I will take pictures of it soon after I clean all the grease off it.
