A lot of other comments already, and one or more may be similar, but will add mine anyway:

>I like language, and this inscription makes me wonder. Why write on a bell that it's a bell? I'd be less surprised if the bell had said "Muhayideen Baksh’s ship".

I think it may mean "the bell from that particular ship" to distinguish it from any other ship's bell or any other bell.

Edit: Could be, in case of theft or loss of the bell (would make it easier to find and restore to the ship). Though of course, someone could possibly rub that writing off with a file or other tool.
