Thanks PhysDoc, I learned something I wouldn't have otherwise, so this peep sight is intended for either target shooter or service rifle and must be pivoted aside to cycle the bolt. I'll need to learn more about the two rifles, I like books sometimes and have even bought a few lately, they have lots of pictures though. More sporting than target, C.G. Haenel, Haenel-Mannlicher, sporting rifle, 8x57 should search. The rifle has a Lyman #36.
