    I don't know specifically about the Special but the 
regular T-P shutters are wound by a cord which runs out from 
the bottom of the shutter. If the double curtain shutter 
works the same way the cord may have rotted away but the 
hole it goes through will be there.
    I have a standard T-P roller blind shutter but the 
shutter curtain has long ago begun to crumble. I have not 
had any success in finding the correct sort of rubberized 
cloth to replace these. The orinal appears to be thicker 
than the cloth used in Graflex FP shutters although it would 
probably work fine.
