I am rebuilding a Regina Corona, model 35.  It is an early model with
the lifting straps.  Would appreciate any advice on the following
topics:

Question 1.  The disc selector (sometimes called the "Index") has
a rotating arrow with a knob which moves a cam and linkage to adjust
the location of the disc carriage.  I would like to remove this
"arrow & knob" from the shaft without breaking it.  The entire
spring motor assembly is still in the  cabinet and the shaft for the
"arrow & knob" goes through the side of the  cabinet.  I don't see
any set screws or pins holding it but the "arrow & knob" is held on
securely.  Has anyone removed the "arrow & knob" and how did you do it?

Question 2.  This Corona is missing the top decorative pediment and
needs a replacement.  Is anyone making these?

Thanks for any advice,
