[GreenKeys] The "Low Down" on Bell Ringers

[Jim Haynes]

And I learned from some archives that the J and S bells were the result
of AP wanting two different bells, one to ring on the machine and the
other to ring in an editor's office.  So one rang on the machine and the
other operated a contact to operate the remote bell.  And somehow after
the need for this had passed the whole world split into two directions
for bell on the machine, one using FIGS S and the other using FIGS J.
