Somewhere I saw a post of Kodachrome 4 x 5 shots taken in WW II defense plants in the US. They were wonderful! Taken by an expert, well lighted, etc. The pix above might have been medium format, certainly that would have been more likely for the Montgomery and King George shot. There were many color movie "gun camera" shots of aerial combat taken, I imagine, on Kodachrome. Somewhere I have a Photographer's Mate manual from the mid 50s. It deals with the Medalist and Graphic 4 x 5, I don't remember whether it discusses color film.
