So my father in-law saw my Mosin and thought I might have an interest in this rifle. I have found info on the manufacturer describing it as a sedish mauser. One question I have is if the barrel has been modified? This gun belonged to my father in-laws brother who served in vietnam and passed away over 15 years ago. no import marks so i don't know if he brought it back from vietnam? any info from those with more experience would be appreciated.
