Don't have any "character" weapons but do have a Marlin 94 44/40 marked "W C Co'" for the Western Costume Company in Burbank ---a movie prop supplier -
It is also marked H. O. P. -- have not figured the meaning of that yet --
Was a Leo when Dirty Harry came out, went a week later and bought a 4" Model 29, 4" since had to fit in the leather basketweave old revolving patrol car holster. I carried it where they'd let me in places that didn't furnish pistols, back then there were many. And I still own one.
