Söderin Diopter Sunshade

This is an m/Söderin diopter sight with a sunshade installed. This is a nice accessory that mounts directly on the front surface of the diopter housing.

This particular one resides on my Husqvarna m/96. It is a bit unususal as it is not cut to enable more extreme adjustments of the elevation. Most I´ve seen seems to be. As you can see here, the sight has the yellow elevation disc for the 790 m/s 6.5x55 139 grain M-41 military ammo.
