First of all, the gradation is in 5 unit increments (1 big mark per 5 units) and not each 4 as in the US scopes

Second, the horizontal reticle is divided in degrees, as you can see the proper symbol above the "5". However, the vertical reticle is in my opinion divided in radians, and that was a common practice in military periscopes/telescopes for rangefinding when no stadimeter was available. German U-Boat periscopes also used that pattern. The horizontal is in turn divided in degrees because its use is for "lead aiming" and not for rangefinding, hence you go back to degrees because that's the unit you also use in the firing solution computation

The only details I don't see now completely logic in the video are:

-Lack of any numbering.
-Exact same division for horizontal and vertical.

Both details are different in the periscope view you posted, but are not essential in any case.

If I were you I would however model the reticle you can positively point at as coming from japanese submarine

I will do the one from the Kaiten type 10 scope.

btw who said it wasn't a very good scope ? the captain of I-47 ! he said those scopes were useless to attack at night and were of poor quality, you have then to imagine that the type 88 periscope had much better optics .

I think that in the video they mimicked the real scope, as filming through a periscope is very difficult as you can see in Gochin.

but I still need better pictures taken through that scope Rubenandthejets ! and.. I know you are dying to put your eye to the eyepiece of that scope !

I know I am...
