Yep, which is why most Beaus only show the individual code letter, and some fighters too. There were exceptions though, as the odd aircraft still had the full squadron code and individual letter as late as early 1943. The problem of identity (today) can be compounded by various books displaying a picture of the same aircraft, often the same picture, with details for different squadrons. Frustratring, but part of the 'fun', I suppose!
