Hi
The gun can be a 1914 navy wish like the 1906 navy have a adjustable rearsight.
In both cases should the barrel be 6" instead of 4".
One reason why the rearsight can have been filed down is the regulations within the Swedish pistolshooting that states that the length betwen the sights should be the maximum of 220 mm.
And i know in a few cases when they shortend the navy barrels that they also destroyed the sights.
