I’ve been hooked on Steve Ginter’s publications ever since I came upon his first ones which more or less amounted to just decent-size pamphlets in thickness, with no color. Since then, I have managed to glom onto a pretty good collection of his Naval Fighter Series and companion Air Force Legends Series as well.
Each successive Ginter book seems to set the bar a little bit higher, being a little better than the last one. For modelers or historians, they contain a wealth of information, photographs, drawings, specifications, and history. I consider them among the best reference sources in my stash for my facets of the hobby.
