Continued cleaning the roof, more than half had been cleaned by the end of the week.  This is a slow but necessary process if work is to continue at some point.  Further illness interrupted this process but I managed to fit the glass into the emergency door frame and started to fit the hinges but ran out of screws.  I also started cleaning the inside of the bus and the seat frames.  I also fitted two of the steel plates to the rear seat back and trimmed the third to fit.  The final act of the week was to collect the remaining seat backs from Ifor.
