The Valiant Tinker is a 1939 Australian radio play by Catherine Shepherd about John Bunyan.

[3] According to Leslie Rees the play "demonstrated the political and religious pressure the writer may meet when he writes his mind, and how he must resist it.

There are no heroics about Bunyan in this play, he quietly prefers prison to blinkers, there is a quality of peaceful certainty in him, he knows what he must do.

Miss Shepherd tells how the “valiant tinker” was converted by a strange happening in an inn from his “sins” of dancing upon the green, playing tip-cat, and ringing the bells of the church steeple.

The story shows Bunyan's intense examination of his own inward life, his being visited by “Angels of Light and Darkness.” his determination to be a preacher, his insistence on freedom of speech—“l say there’s no freedom except a man may think as his conscience directs him and speak out boldly the thought in his mind” —his incarceration for refusal to curb his opinions, and decision to write “The Pilgrim’s Progress”.
