    Figs-J is BELL in ITA2, found on Western Union machines.
(AT&T and military machines are usually USTTY, which has BELL
on Figs-S.  BELL is a special case.  It's the only non-printing
single-case character.  LF, SPACE, CR, FIGS, LTRS, and NULL/BLANK
are the same in both cases, so they can be made non-printing by
just omitting that typebar.  BELL, though, requires a special
mechanism to make it not advance the carriage or tape in FIGS
shift only.

   But perforators punch everything.  They lack the
no-tape-advance mechanism that 14 tape printers have.
So it has to print something for BELL.

Here's the detailed typebar table for a Model 14, showing all
the valid options.

"Check carefully the arrangement of pullbars in segment and
the arrangement of pallets in the typebars.  If these differ in
in any way with the arrangement shown on this page, the parts
should be ordered by name."
