Not receiving any feedback here, I went ahead and bought it.
There is a lot of duplication of photos, which is not a surprise. There are a couple of squadrons where there are more in the windsock book, but not many. In the windsock book, there are a lot of profiles which I always welcome.
Am I glad I bought it? If someone is picking between it vs the British Aviation squadrons book, I would probably recommend the latter, just because the latter covers a lot of other squadrons and has some more elaborated text about markings in different timeframes. But if someone is just interested in camels, this is *very* nice. I'm not unhappy that I bought it and I'm sure I will get a lot out of the profiles.
