Some late M-3s and M-2s had two notches, one above and one below the
rangefinder patch. One is wider than the other. By comparing the spread of the
two images in the rangefinder to the limits of the notches a rough indication
of the depth of field is indicated.  I find it difficult and use the depth of
field scales on the lens instead.
