when looking for a new hunting bag for xausa I stumble about a exibition catalog http://docplayer.org/80606102-Vogeljagd-in-der-provinz.html - bird hunting in the province -

about the life of alexander koenig https://en.wikipedia.org/wiki/Alexander_Koenig

they had also his shotgun a 16 ga lefaucheux which he buy on tick as a young man in the 1870s. for sentimental reasons and because he was satisfied with this gun it was used by him up into the 1930s.
Koenig use this gun on expeditions into the artic and to the nile but it is nonetheless in great shape.

the tool you see here over the gun is the cartridge extractor for pinfire shotgun cartridges

allways look for such a thing but never find one for sale

and if we look at this pic with koenig ...

there it is

would be hard to find this tool on another hitorical picture again, thank you for your attention
