Other than the one in our collection, we are aware of just one copy of this manual. It is located in the collection of the US National Archives and Records Administration in Washington, DC. We hope to visit the national archives soon.

Hopefully, a couple more will pop up in someone's attic or buried in a storage room at a Navy base.
