Searching for WWII American Submarine Oral Histories

[ejc]

I am looking to find unpublished oral histories of submariners who served aboard the USS Cod specifically, as well as six other boats generally. I believe that I have managed to locate most, if not all, of the oral histories that have been published or are stored in archives. Thought that it wouldn't hurt to ask. Someone on here might have a diary or other written accounts from crewman who served aboard these boats. This is for research that I am conducting for the USS Cod Submarine Memorial.
USS Blenny
USS Muskallunge
USS Ray
USS Spadefish
USS Bluegill
USS Crevalla

Thanks!
