My father said everything he could read he wrote to me, and I posted above. I'll look over it this weekend for anything else. It does not have a front site - I'll look for marks.
One question I DO have, though - if it's based on the 98 Mauser action, why do the numbers on the barrel, as well as bullets he have seem to be an 88 (.318)? Or am I misunderstanding something? (very likely!).
Thank you all for sharing your time and knowledge.
