Does anybody know the date The Missing Chums was originally published? It's the only one of the originals I can't find a date for beyond 1928.
It was released in 1928. As I recall, McFarlane, according to his autobiography, did not receive the outline till closer to Christmas 1927 or just within the first couple of weeks of 1928. So "The Missing Chums" probably wasn't out till Sepyemberor closer to Thanksgiving.
