Manual of Arms

I found it after searching in the 1940 Bluejackets Manual in my maritime collection. It’s not something that I refer to very often. However, I have it on hand when I need to look up obscurities, which was one of those times. I had made some stupid comments that upset my wife, and wincing, I mentioned that I should do the 99-count manual of arms 99 times. She had no idea what I was talking about, but appreciated that I was apologizing.
