Thanks to Norman Brown who preserved a VHS tape of a BBC Television broadcast of the official Uniroyal promotional film, we have a visual record of the event. The first part of the film was a summary of the first six years of the World Junior Championship, which has already been mentioned on the Curling History blog. That link is here.
In the semifinals, Scotland beat the USA, skipped by Ted Purvis, but most of the film is about the matchup between Canada (Denis Marchand, skip) and Sweden (Thomas Norgren, skip). Watch this here.
Part 3 is the Scotland v Canada final. To watch a thirteen minute summary, go here.
Bob Picken narrates in each clip.
All the details about the competition, including the names of the competitors and the results, can be found in the World Curling Federation's Historical Results site, here.
The Scottish Curler magazine in September 1981 featured the team on the cover, Marlene Dawson making a special presentation to the four Stranraer curlers at the Annual Meeting of the Royal Caledonian Curling Club.
