I traded for a mauser last night but don't know anyhting about it. On the left side of the receiver it says mauser modelo argentino 1891, manufacture loewe berlin. I looked at online pics but mine has a bent bolt handle unlike anything else I saw. It has had the stock cut and reshaped at some point in its life, but is still a very nice gun. What ammo do these shoot? And also about what are they worth? Any help and input is appreciated.
