Hi BigWalleye, that photo you mentioned is not looking through a periscope. It's looking through one of the eye pieces of a TBT (that's the Nautilus conning tower in the background).

I forget which side it was, but the stationary lines within the one lens is what you're looking at.

I don't have a picture of what the Stabilize Azimuth Line would have looked like within the Kollmorgen Periscope. Guess it was just a vertical line, separate of the Telemeter Divisions within the lens.

From the instructions on the thing, I get the impression that it is a pretty fat line too. If it was as thin as the regular lines on the optics, using one side of the line as reference would probably be a non issue in practicality I think.

I'm also pretty sure it wasn't holographic from the description. It was probably literally a plain black metal bar that would move across the periscopes eyepiece at a rate determined by the gyrocompass, periscope bearing, and submarine speed.
