Markings on "14k & Sterling" Keys/Case

[blp20151]

I was unsure where to post this request as the item is marked "14K & Sterling" (seen in 3rd Picture). The middle mark a "D" or "B" has a sword struck thorough the letter (more visible in 2nd picture). Also, the case itself has the letters R.F.M. (3rd Picture) which to me looks like some type of personalization but it belonged to my grandfather and those are not his initials? I'm just tying to find some history on it and I think finding out what the markings mean will be a great start! Any help will be greatly appreciated.
