Our library does not own any microfilm or other items pertinent to the National Archives Record Group 36, M972.
As best I can tell, the LDS Family History Library in Salt Lake City is the closest institution that may have the microfilm. Even so, the information I'm finding is cryptic and I'm not sure of that.
