Hello Henrik!
I see you have few posts and joined in December, so Welcome to the group!
That is an interesting machine you have, thanks for the picture.
I assume that's all new paint that you put on.
Do you have any "before" pictures you can share?
Do you have all the parts? Is there a jack/base under the vertical screw lift for the knee? Or does that bracket under the knee support the entire knee?
Also, it is difficult to know the scale of that mill (Is it a floor or bench model?), can you give us some basic dimensions, like the table size, over-arm diameter, and total height? That might make identification easier.
Does it have a tapered spindle? if so what is the taper?
I will browse around over at:

to see if I stumble across anything identical or even similar.
Good Luck!
