In the course of a much-needed clean-up, I came across the following device. I no longer have any idea how and when it came into my possession; perhaps the optics interested me. As you can see, the device consists of an optical system, which, unlike a magnifying glass, reverses the image. With the pin on the side, you can pull up and fix a movable hammer. Pressing the trigger releases the hammer and the small conical tip punches a dot into the base. There is no scale in the optics, so it is probably not a hardness tester. As an optical centre punch it is too inaccurate, as the example in the last picture shows. Also, it is very difficult to place a cross line exactly between the lines in the optics.

Any ideas what it could be?
I was a bit lazy and used Deepl translator; I think it (he?) makes a good job.
