This is the final “Donald Duck 10-pager” by Carl Barks for Walt Disney’s Comics and Stories. Daisy and especially Gladstone are redesigned toward sixties sensibilities.
Inexplicably, Chief O’Hara is called “Captain O’Hara” in this story. Bob Ogle story credit by Joe Torcivia. October 2019. Previous indexer listed Vic Lockman. No indications of "Vic Lockman style dialogue", more humor exhibited than in a typical Vic Lockman story, and this tale appears during a time period when Bob Ogle was writing for Western - including some Super Goof stories - indicate this is more likely Ogle than Lockman.
