I don't have mine in the hand right now, but I think this should be the indicator for focus correction when using infrared film. Focus normally, check the distance and correct it for IR by this distance...
Butkus has manuals.

No ; there is a dual mark on the focus lever knob that I assume is for IR film.
I am referring to to the focus scale.
I think it has something to do with achieving maximum DOF for snapshots .

Sometimes those marks are an indication of the hyperfocal distance, for a commonly used aperture - say f/11. You might use that if you wanted to set the distance to one point, and then not change the focus while you took photos of your visit to the beach or some other such "snapshot" endeavour.

Yep. On the aperture scale alongsdie the lens, there is a '7' in red, indicating f/11 (light value system) while the other numbers are in black. So set focus to the red 6 meter (15 feet on my English scaled one) and the aperture lever to the red 7 (for f/11).
