A slow start to the week.  I finished spraying brown on the various parts of the cab window frame, then drilled a 4m length of  half-round beading; in 100 holes, I managed to get one slightly off-centre.  I decided to use this for the curved section and the short piece for the emergency door, which may allow me to omit the off-centre hole.  I cut and  fitted the curved rear corner piece up to the emergency door the following day, then fitted the vertical wind deflector and beading to the to the emergency door with the handle recess casting temporarily in place.  I am unsure that the beading is correctly aligned at the moment though.  However, I decided to proceed with the beading and drilled and started to countersink a 4m length of half-round to complete and fit on Monday.
