Hille, & HuwG: as I understand it, the maker of Pugwash has denied all claims about these three names, and threatened court action about their appearing in print, as a personal slur. I know that for the repeats, it is quite clear that the one character is referred to throughout as "Master Mate".
It was easy for these claims to arise in the days when video recording was not available, and claims about the previous day's TV shows could not be confimed.
