World War II era U.S. Army “ONI 41-42 Japanese Naval Vessels” Reference Book

This is a World War II era U.S. military reference titled “ONI 41-42, Japanese Naval Vessels” which bears the original “RESTRICTED” marking in the upper left corner. This text comes in the original box which has some slight wearing along the edge, but otherwise is in excellent condition. All of the original pages are present, and few if any show marks of age or wear. The original quick-reference pages are all present (with titles such as “CARRIERS” and “DESTROYERS”) and show every known vessel within the Japanese Navy at the time of publication. All of the original images are clear and easy to see, and it would be difficult to find a more complete and better example of this piece.
