I have already done a video on this relic, you can find a link in the description (teardown, overview, etc.).
It looks alright, kind of fuzzy, probably just due to the age of the device and the fact that it was not a super precision instrument even in its day.
If anybody has any answers to the questions I ask in the video, telling me in the comments or here would be awesome.

Thanks!
