Hi Hitman!
We were referencing your mods, so, perhaps, you are the person who can clarify this a bit more!

It is quite obvious that films can, and often do, get these kinds of things very wrong.
Still, I believe the photo on the first page to be genuine. Is it not an actual shot from the time?

Anyway, even if this particular picture is not real, it does show the seemingly ubiquitous centiradian reticle.
Seriously, all the film people use it, there must be some source where they got it, right?

Further, I trust that this exact reticle is replicated in your mods. A similar one in mods for Silent Hunter V.

So, can you say, whether there is a specific periscope, or some other optical instrument, that this centiradian scale is based on?
