So a project in the near future will be to recreate Sea Fury 1st prototype SR661. This had the shorter vertical tail, short hook and a four-bladed prop, at least at first, which is how I intend to model her. My question is - what colours was she painted in, specifically the undersides? During WWII, British prototypes were often painted with Yellow undersides, and that is how photos of her look. BUT these photos could also be interpreted as MSG or Sky, and I have seen profiles with both. What is the learned opinion of this forum?
