Kagero has issued a series of “References for Modelers”, each focusing on a specific subject. In this case, the P-51B Mustang. The format consists of color artwork, photos, and line drawings in two scales. A bonus decal sheet is included, along with color artwork in the centerfold showing their placement. Up front, the book explains that most of the photos have appeared elsewhere, but this series presents them differently. They have been enlarged enough to show details lost in smaller formats. Two great examples appear on pages four and five, one showing a close-up of the equipment behind the pilot’s seat and the other a nice view of bazooka tubes on a P-51 in China.
