1942 is easily the most common of the wartime editions. One with a dustjacket is less so. This dustjacket is rough and suffers from some loss but has been repaired with archival tape. The cover itself is bright with only minor bumping and a bit of rubbing along the bottom. The hinges are unbroken and secure although there is a light shake. The textblock appears to be unmarked. The toning endemic to Macmillan editions is fairly light. It is not ex library. #466. Click on "Warship Observer" above for complete listings, including 100+ JFS.
