Storyboard

Storyboard was an anthology series Thames TV used to air drama pilots in the 80's. The missing episodes were later developed into series and are found with those series with the exception of Lytton's Diary, which is found here and not on the Lytton's Diary discs. (I didn't have it at the time.)
Those are:
4 - Woodentop.......now serves as the premier episode of The Bill
5 - The Traitor.......became an episode of Mr Palfrey of Westminster
8 - King & Castle..became the first episode of King & Castle
9 - Ladies In Charge...found on the Ladies In Charge disc.
13 - A Question of Commitment....found on the Mr Palfrey of Westminster discs.
