The next pages will help you to understand the working and the adjusting of the Kalart Rangefinder.
However, if you have a Graflex with Top Mounted Rangefinder click here to visit my pages about the Graflex Rangefinder.
As far as I know there exist 2 types of Kalart rangefinders. The earlier aluminum housing rangefinder (1) and the newer steel housing rangefinder.
The newer type steel housing rangefinder with rounded edges has a window on top of the housing to attach the Kalart Focus Spot.
There is one type which has a screw on the front (fig 4) to adjust the lateral coincide.
The other type (fig 3) does not have an adjusting screw.
The silver colored steel housing range finder ( fig 2) misses the adjusting screw as well.
