Nicely done, good pictures, although I had a heck of a time trying to figure out where it was taken (I can see the ears, but wheres the mainspring?)
The first Krieghoff markings would be the same, until they had used all the parts; krieghoff always stated that they made their own tools (see Gibson)
There is NO vickers tooling, since they were DWM parts?

PS: Put them altogether
