Thank you so much for your replies! I already love this forum!
I will upload some more pictures tomorrow, if there is something particular you want me to take picture of please tell me :)
Until then this is the info I now got;
A reddit user has done an incredible job identifying this piece.
The information he provided makes a lot of sense.

This means that Rezdog might in fact be correct. Late 1700s sounds about right.
I definitely want to renovate it. I do not want to use the stub tail. (Hope I got that right) Not the 1940s razors either, I rather buy I new one. This kit already means something to me, I would rather pay for a new razor. I have one problem and that is that I live in Norway. So there is very few experts on this area in my country. However I saw that you have a "nordic" forum here. I going to try my luck there and see if anyone knows about someone from Scandinavia. Or is there something else I can do?
