RF questions

[Paul Howell]

Question: How would you determine, aside from shooting a roll, if a RF was out of alignment? Mine seems OK and everything, but I was wondering how one would determine this? Would it be the double images never line up or something like that?

Over the years I have had misaligned rangefinders in my Crown, 150mm for a Maymia Universal, and several 35s, in all of my cases the images are out of alinement at infinity.

There are two kinds of misalignment: distance (if infinity is OK, so will the rest be with most 35mm cameras) and vertical, i.e. the inages at infinity match left-rght but are one above the other.
