This cartoon (along with other "Hook" cartoons) was found by accident in the garage of a former soldier who had saved them, thinking they were "Private Snafu" shorts. The cartoon was finally discovered in the mid-1990s when an A&E documentary on war cartoons began production. It turned out that Warners made these shorts for the US Navy and because they wanted to keep this a secret, all original negatives were destroyed shortly after release. The "Hook" shorts that were given to the cartoon researchers had "vinegar syndrome" and have deteriorated, but fortunately before that happened, they transferred them to video. ~ Source; IMDB.
