check the first post (its updated) you will find there my mod with the reversed range finder scale at uzo.

@Pisces:when you are saying that the uzo ( in real life ) didn't roll ,you mean that it wasn't moving vertical at all ??(i did it to move a very little more down in order the above red horizontal line to 'catch' the horizon)

@Hitman:right.this explains for what was the marks of vertical scale that are lower from the horizontal line.
the marks of vertical scale that are above horizontal line are propably had use for the stadimeter
