It's a beautiful little creation, but uses a modified (coloured over) cockpit canopy. Various techniques have been used to create these effects in the past including acrylic inks, stains and thermal sheeting. Peter has done a great job on this, but not one for the purists I fear! The lack of variety in trans-yellow parts has always been a double-edged sword, an annoyance, but a challenge. Try coming up with some novel trans solutions and get those pictures on-line!
