Large color-mixer for four disks, two upon each spindle. After Wundt, by Krille, Leipzig Some of the 60 cm diameter discs that Muensterberg lists as <link ref="tec2952">"Color Mixer Discs" (No. 72)</link> are in use in this device. Note that there are three discs shown on the image. Only two of them belong to the color mixer. Two smaller disks are mounted on each of them. The third wheel (on the right) probably belongs to another device. See the <link ref="lit8140" page="p0004s0002" mk="0.775/0.6514" >same device</link> on the cupboard in another image from the same set.

                   Muensterberg’s Nr. 71, “Large Color-mixer for four
                   disks, two upon each spindle.”  I  must have
                   written down the wrong number., These are  some of
                   the 60 cm  diameter discs Muensterberg lists as
                   Nr. 72., Krille, Leipzig.  I do not  have a Krille
                   Catalogue but I based the decision on the ratio of
                   the size of these discs to  the large Newton Disc
                   (M75) which was given as 80 cm in diameter.  But
                   these discs  appear to be connected to something
                   behind them, perhaps color mixers.  The following
                   image [Related: img30045] shows more of the 60 cm.
                   discs that are not connected to anything.  Comment
                   III (per Mail): There are three discs  shown side
                   by side in the IMG 30170 image.  Two of them,
                   shown in the attached snip [shows only the two
                   disks on the left,  img sent by mail], is the
                   color mixer, M 71.  It is a large color mixer for
                   four disks, two large and two small ones.  The
                   third item, the one on the right of these two in
                   the IMG30170, must be another color mixer but a
                   separate device.  http://vlp.mpiwg-berlin.mpg.de/l
