[GreenKeys] model 28 excessive line feed suppression

[Ken Stritzel]

If anyone is using a model 28 teletype and has excessive line feed suppression
enabled in the stunt box, please review my list of parts as I would like to
install the feature in my 28 KSR.  I think the below parts will limit line feeds
to two lines:
2 - 152668 LF Function bar, no restrictions
1 - 155130 LF Function bar, non-print
3 - 157240 Spring
3 - 152653 Pawl, Function
1 - 152660 Latch
2 - 154613 Latch
2 - 152121 Lever, Function
1 - 152642 Lever, Function

Did I miss anything?
Suggestions are welcome!
