[R-390] RF rebuild

[Biddle, Richard]

From my deep dark days of repairing teletypes, I managed to hang onto a
couple of spring hooks.  I never thought I would need them again until the
R-390A RF deck appeared.
http://www.tecratools.com/pages/service/spring_hooks.html was them for less
than $5.00.  Having them saves making up new cuss words like "dog crotch" :)
