This is a tiny contribution - others have far more experience.
A continental version of the T-P shutter. Problem - Broken "cocking" thread.
The obvious high-tech modern solution was to steal a section of an IKEA sunblind.
The working end has just to be threaded through a hole in the end of the top roller.
Impossible, the diameter is just oversize enough to be refused entry and the thread is not rigid enough to pushed at an angle.
Back to the original material which is cotton. I asked one of my daughters who is a dressmaker/jewellery making expert. She recognised the original thread as a "waxed" thread which had lost it's wax covereing. Yes, she some lengths I could try with!
This is a great material. The wax coating gives reduced friction to the mechanism and it stays stiff when pushing through the tiny hole in the wooden roller.
In the illustration, the hole is concealed between the end of the shutter material and the wooden box framework (top left). The thread passes through a cutout portion of the box and exits through a hole at the top right.
I suppose the IKEA thread could also be installed - but this would require a complete strip of the brass parts!
