A slow start to the week.  Painted a thinner coat of brown on the cab door inner panel, a better finish but the second coat look good.  Primed thewaistrail and the window surround  on the cab door and   applied a second coat of No.1 rust-beater to the plain window aft of the cab door, after rubing down the first coat.  While the paint was drying I assembled the sliding pane frame of the cab door window and gave it a coat of the correct brown, it will need another.  Applied finishing filler to the slight depression on the front corner quarter panel and to the roof just behing the emergency door.   Final job of the week was to start creating a pattern for the front mudwing, for which I used a long piece of thick card from an advertisement.
