I don't know if those records would have stayed locally or if the Navy would have taken them. Here are some local contacts:
Blaine County Historical Society, PO Box 124, Hailey 83333, 208-788-1801.
Ketchum-Sun Valley Historical Society, 180 First Avenue East, Ketchem 83340.
There is also a look-up volunteer in Blaine Co. Go to http://freepages.genealogy.rootsweb.ancestry.com/~obitl/voli...
