Thank you (and some others) for the help/reply.
I just read a Japanese book on M cameras (by Mr. Shin-ichi),
in which he also mentioned the static electricity problem
when discussing the differences between glass and metal plates,
and between DS and SS film advances (the DS was to avoid
the static electricity too?).  I can understand only
about 10% of these Japanese characters, but I think what you
said is correct.
