The Spokane Chronicle front page read "Sailor Dies in 'Gruesome' Accident" in November 1944. This paper was delivered to Fred Jackson on August 3, 1945, apparently, in Box 432. Is this a former owner? Is this the date the ship lap was installed around the large south facing window where the paper was found? Impossible to know for sure, but it does give a better approximate date than "probably before 1960."
