I have a similar Norwegian Krag made during the occupation. Same rough finish, marked with Kongberg's simplified crowned K "Tool Mark" , no final to scabbard, and ufortunately no waffenamt.
The scabbard is numbered 43. I use to believe it to be the year of production, but Denny's Krag seems to be serialed.
Many more bayonets than rifle were produced during 43 / 44.
