Here is strange one. It is a screen capture from a Youtube video about a warehouse of leftover Spanish built fighters used in the movie "Battle of Britain". This photo is from a set of historic stock footage at the beginning of the video - which do not have much to do with the rest of the video. The main gear seems very widely spaced and outward retracting, there is a strange bulge in the wing, and a 4 blade paddle -like prop - maybe a high altitude modification? What is under the right wing?
