Need more info about optics of a periscope (SRC/16 of the Seehund)
 

I need some info about a periscope for my upcoming iOS sub sim
http://www.subsim.com/radioroom/show...32#post1937293

The Type XXVIIB5 Seehund (also called Type 127) used the SRC/16 periscope.

So far I know:
- It was a fixed periscope (2m/3m length early/late models)
- rotatable by 360° on horizontal axis
- Magnification 1.5
- Field of View 38° (not 100% certain)

What I need to know:
- Some sources say it was able to tilt - how many degrees +-?
- any filter glasses?
- was there a visible bearing scale?
- what kind of graticles and rectile?

Unfortunately the best book about periscopes I own "Vom Turmsehrohr zum Optronikmast" had almost zero information about it. I've searched a lot but it seems impossible to find anything. Please reply if you know anything that could help me, thanks!

Thank you, I know this PDF but it does not help with this special periscope.
