[ Ref 050424 MMDigest, Musical Box Controls Marked Z & V

It turned out that the subscribers to MMD didn't know what the V and
the Z stand for, but maybe I am more successful by asking again.

This time the musical box has three plates.  The first plate has the
inscription 'REPAT'.  The second one reads 'STOP' and the third one
says "Vr van As".  The small 'r' and 's' are in superscript with two
lines under them.

Is there anyone who has an idea?

Kind regards
