I have been given a Norwegian Krag. It took a lot of research because everyone thought it was a 30 40. The wood on top of the barrel is missing and it is a carbine. It has numbers on the receiver,barrel and rear site. It also has 1910 stamped on the receiver. It also has two notches in the groove on the left side and notches which suggest it once had a scope. The serial number starts 89...  I am interested in a possible value and if there are cartridges with low pressure as it seems there is a safety problem with most modern shells?
