Steve,  I have attached a picture of the cutout control valve on my
late model 105.  It looks like you are missing the pneumatic and you
have only the attaching block there.  The tubing goes directly from 
the pneumatic to a nipple on the stack for the "Rewind".  This actuates
the small pneumatic, which pulls a metal rod forward that then engages
with the rotating upper shaft, and starts the rewind by pushing down on
the lower shaft.
