I am a fan of the Haynes Manuals, which, depending on the author vary from the merely "good" to excellent.I have this book and Mark Healy does himself a disservice when he says the book is simply a guide, as it is much more than that, as are his other Manuals in the series on the Panther and the T-34. I also have some of the other books he suggests as further reading, and quite frankly from a modellers perspective they add little to the information contained here.
