identify this tv show - Man who kisses the daughters of the boss of the branch office he's sent to close

I'm looking for a British TV show set in the 1930s maybe (?), only has a few episodes.

The man kisses all three of the manager's daughters in various charming British misunderstandings, once sitting on a ruined wall in the gardens of a mansion. In another scene, he paints a daughter in the nude.

The first episode ends with him and one of the daughter's dancing the Charleston on an old steam train which the manager likes to drive around on.

I saw the first episode of this years ago, it was really funny, I'd like to watch the whole thing but I don't know the name.
