Hopefully you have an optical sight on your drilling, than you can use this. The rear iron sight goes only up by cocking the rifle barrel. You can also take it up by hand and block it with a small piece of iron in front of the sight on the rib.
The Einstecklauf is adjustable with a small tool and after that's done the drilling get a mark on the barrel for ever how to insert it.
I use it in my August Wolf Drilling (manufactured 1926) and it's perfect together with a Hensoldt 4x for cat and fox.
I have the original description from "Krieghoff-Einstecklauf Semper" D.R.G.M. (appr. 85 years old) to adjust it and I can send it to you as a copy.
