Alan kindly referred me to three videos on his youtube. The films were made in 1960 by Coventry Film Production Unit which I understand were based at the Umbrella. If anyone can provide further information on these films or the production company, please get in contact or leave a comment.
The first film is called - A Visit to the Dentist
All's Fair in Love and War - 1960
Featuring - Zena Brandwick, Patricia Dalton, Peter Martin, with Eric Smith, June Sheffield, Martin Lovell. Photographed by John Archer Hall, assistant cameraman Martin Lovell, story and production Ken Pearson. Directed by John Allibone.
Alan says - "Another film from Coventry Film Production Unit. Circa 1960. Black and white and silent. If you have any info about the group I'd be very interested. It's a little melodrama about being careless with your loved one, something of an object lesson."
Symon Enry comments on the youtube page -
"F.Y.I At around 7.25 you see the couple walking down Daventry Road away from the Parade and they have a snog on the corner of Carthusian Road. Just thought I'd mention that to nobody that will ever read this or care."
