Very common fate of bringbacks, these make very handy and light hunting rifles... do the right side of the receiver and look closely at the buttplate for markings, also the wrist (small) of the stock for ordnance work. This rifle stayed in government hands after the war, in actual military or police service, these (98a) are often fairly original and sometime unit marked (buttplate usually)
When you start you project (restore) take a shot of the barrel code, it should be just below the stock line near the barrel serial.
