Started the week by freeing up the destination  blind winding gear, then fitted the spring plate and bulbs.  A quick application of power revealed that the wiring is sound.  Tried to fit the blind that was in the bus, only to find that the rollers were slightly too short, so some modification is required.    I found some tube that was suitable, so made new rollers of the correct length, which required some engineering to fit the end pieces, by boring out the internal diameter by a few thou in the lathe.  I was working on the last end piece at the end of the week.
