Query: worth the money, if you are obsessed with this aircraft

Yes, the title is a bit misleading, but by industry 'standards', not nearly as misleadiong as others. It's not as if it suffers Bowman's Syndrome, that strange affliction cast on the Mosquito.Perhaps ironically, the best way to retrieve information about the machine in general or a type in particular is to have the Prien and Rodeike masterpiece, 'Messerschmitt Bf109 F,G & K Series: an Illustrated Study' spread out on the desk beside this one. Then you have all the side views, the best mix of photographs and, with the 'Recognition Manual', the clearest explanation of sub-types and field modifications.If these two books ran into each other in the street, they could be combined and make quite a lot of other Bf 109 books redundant.
