Ran into my retired admiral pal. He says definitely a police gun with that "kei" marking. Also says just read it left to right all the way around: Meiji 29 [1895] Police 1043. Says the arabic zero was common enough at the time. As for the other marking, he thinks "two two" in kanji followed by arabic 23. No explanation for the extra marks that make it look like something other than two, and no guesses as to the meaning. I guess some sort of inspection marking.
Do post back when you get the letter. Very cool to have a late Meiji period police gun, I think.
