I doubt that she was my uncle's boat, Mike, since you said she was commissioned in 1943 and stationed off Alaska for the duration. My uncle served in the western Pacific and in fact, went ashore in Japan when the war ended.
It was once a 1942 minesweeper which John Wayne bought in 1965
Wonder if it's possible to determine the minesweeper's WW2 name or bow number? My favorite uncle served aboard a minesweeper in the Pacific during WW2 and that would be a thrill to discover that he served aboard the same boat Big John bought.
He's long dead but my cousins (his kids) are naturally still alive and they'd probably get a kick out of knowing the same information.
