Long sought after... one of the rare self-loading rifles from ALK Waffenwerk / August Lüneburg Kiel "System Rohde." There are various DRGM numbers associated with the weapon and a patent from 1923/ 1925. As always, I am now in search of everything related to this weapon and August Lüneburg, including serial numbers of other weapons, advertisements, etc.
Every little info is welcome!

The shop in Kiel 1965, still named "ALK Waffen"
