[GreenKeys] Stunt Box Corrected, Restoring Missing Characters

[Nick England]

Hi Paul - they are type "pallets"
The spring is 157238 - yep, one spring per pallet
Paul Cembura (RTTY Electronics) should be able to help out

Info from http://www.navy-radio.com/manuals/tty/1149B-6705.pdf
Note 26: (Figure 51) The old and new style type boxes may be
identified by the depth of the Pallet Box Front Plate
(new style being shallower). The old style pallets cannot
be used in the new style type boxes. New style
pallets can be used in either new or old style type
boxes. The old style 150077 Pallet Spring is no longer
available and is replaced by a new style 157238 Pallet
Spring. Only the new style spring can be used universally
with either the new or old style typepallets and
typeboxes. However, the old style springs can be used
with the new style pallets in an old style type box.
The old and new style pallets may be identified by the
length of the shank from the rear of the pallet head to
the far end of the elongated hole. (The old style being
the longer- See Figures 50 and 51).
