Hi Penpen
There is/was a conversion kit to make a pr1g in pink around because i made one.at the moment i can't find out who made it but when i do i'll let you know.
MPM do a kit for the pr mk xi and either themselves or SMER did a kit of the pr mk XIX.this kit comes with an etched brass accessory fret (cockpit and wheelwells).
As for paint a company called Xtracolor do both pru pink and blue.Aires do a vacform canopy for a pr1a. this is all in 1:72 scale. I'm just perusing the Hannants catalogue and see that CZECHMASTER have a kit (resin) on the way for the spitfire speed version/pr3 recconnaisance aircraft.
Hth
Regards
Peter
