Trivia

The survival rate of the series in the archives is rather hit-and-miss: from the first season, six episodes are presently known to survive, as with season four. Thereafter, there are sixteen surviving episodes of the second season, and two apiece from the fifth and sixth seasons. The final season still survives intact. Camelot on a Clear Day (1970) is the sole example still preserved on its transmission format of colour two-inch videotape, the remainder being monochrome 16mm film recordings. Additionally, a remount of You're Not Going to Believe This, But... (1969) was made on colour film as an experimental test piece with a different cast, though this was never broadcast. Two off-air soundtracks also survive: Kitchener Knew It Well (1968) and Really, She Did, She Really Did (1969).

For the first season, this show was titled "Mogul" (after the oil company around which the series revolved). This was changed to "The Troubleshooters" from the second season onwards.

Three novelisations were published by Souvenir Press/Corgi Books:

• "The Mogul Men" (1967) by Peter Leslie: comprising Out of Range (1965), Borrowed Time (1965), Join the Club (1966) and Where the Carpet Ends (1967)
• "Wildcat" by Conrad Frost (1968): comprising Kelly's Eye (1965) and Wildcat (1965)
• "The Big Rig" by Conrad Frost (1968): comprising Happy Landings (1966), Safety Man (1965) and The Schloss Belt (1965)

Additionally, series creator John Elliot adapted three of his own scripts for "Mogul" (1972), part of the Longman Structural Readers Stage 5 range for students learning English. The stories were Where the Carpet Ends (1967), A Truly Exotic Development (1970) and There's This Bird, See... (1969).

The series' theme tune was composed by Tom Springfield, the older brother of Dusty Springfield. His own Tom Springfield Orchestra performed it on a Philips label 7" single ("The Mogul Theme", BF 1423) in 1965.
