Hello Mike,
Mauser in 1985 produced a limited numbers of the Artillery Sight Adjusting tools to be associated to the 250 Artillery Commemorative they made.
The tool is very well made and Mauser stamped. They are really rare and almost impossible to be found not associated to the Commemorative LP08.
Several years ago, during one of my annual visit to the Mauser facility in Oberndorf am Neckar, I have acquired the last three available.
One is for sale, I keep the others in my collection.
You can see it here with the price:

You see also my email address if you want to contact me for additional information.
Greetings,
Mauro
