Below: I have not seen another one of these Parker booklets before - THIS IS PARKER. It has some great images and notes. Although there is no date, I am guessing around the 1970's.
Below: I bought this P25 Green trim MKI FP off Ebay in July 2014 for £81, probably a bit over the odds for what it is. It did also come in the rare triple box. Although the main reason I bought it was for the leaflet as it shows all four main colours including the rare Orange trim. This leaflet also supports my theory that the orange trims were only sold abroad as the literature is all in Italian.
