The scopes i rolled into this little mini combo mod i just fell in love with when they were released back in the v1.2 days. They were done by l3th4l and Cox a long time ago over
much discussion and have since evolved into
better scopes 1.5.1
For some reason i liked this version in particular. I think this version was a balance of playability, realism, brightness and view. Nothing overdone well balanced. I like the overall picture that your presented with when looking "at" the periscope. Especially the writing around the scope rubber, the physical size of the viewing area and how the background (or lack thereof) is very proportionate to it.
I was packaging up doing both versions of the Nomograph (imperal and metric) back in the 1.1 1.2 days but have since been partial to just the imperial one. If your doing metric im almost willing to bet you could dig up a Metric Nomograph.dds somewhere around these boards and then its just a matter of swapping the dds and making sure the name of the file jives with the menu entry.
