The copyright date at the end of the closing credits of this episode is wrong. It reads "MCMLXXVII" in Roman numerals, or 1977. The "V" should have been another "X," which would have given the correct date of 1982.
Was this used for the two part Syndicated version? The original version is treated as one story, runs for two hours (96 minutes without commercials), and just begins with the opening titles.
