[GreenKeys] ribbons

[Jim Haynes]

Yeah, I think after nylon ribbons became available the customer got to
choose between cotton for  holding lots of ink and nylon for durability
but running out of ink prematurely.  It was probably only hams who would
spend time re-inking ribbons rather than just replacing them.  Well there
was the military with third-party ribbon re-inker attachments.  I don't
think anybody else tried to use them.
