From the publisher:

Justo Miranda is the author of books and monographs on aviation since the 1980s. A widely known historian, Miranda specializes in aviation of the 1930s and is the author of two volumes on aircraft used during the Spanish Civil War. The exciting discovery of a microfilm on secret German weapons in the early 1990s drove him to publish Secret Wonder Weapons of the Third Reich, later published by Schiffer in 1996. Since then, Miranda has published Reichdreams and monographs on little known airplane projects.

Mig Jimenez, over the past several years, has created a thriving business

based on model paints and eventually, his product line expanded into all aspects of plastic modeling. Significantly, AMMO has produced a plethora of weathering products. These have become so pervasive that words like pre-shading, post-shading, washes, filters, pigments, modulation, and pin-washes are now part of our every-day modeling vocabulary. Trying to navigate all these products and techniques can be daunting. Luckily, Solution Book 13 goes a long way to help you understand and use AMMO’s weathering system.

The author, Wikold Koszela, has written 24 books on warships, mostly British, United States and German battleships and modern Polish and Soviet Navy warships. Twelve of his publications are in the Kagero Top Drawing series. For this and other books, Witold also supplied the line and color drawings, and they are top quality and very helpful for modelers. I could not find additional information on Witold.
