Full titles read: "The Mechanical Masters - filmed at Birmingham." (new title) "Old methods of hand-testing racquets, tennis and golf ball are today giving way to machines, diabolically accurate in their action and impressive in their power."
Birmingham, West Midlands.
Various shots of a machine being started up that tests tennis balls and racquets; some factory girls watch it in action.
Intertitle reads: "The balls are travelling so fast you can only just see them flash by - (except when our slow-camera reveals the action.)".
Various shots of the girls watching the tennis balls fly out of the machine and onto a board opposite. Then in slow-motion we see the balls flying more clearly from machine to board. A man off-camera says the machine is used as a durability test.
Intertitle reads: "Another "Robot" tester for golf balls."
A man introduces a golf ball testing machine; it gives an even blow to every ball. Another man is seen winding a large weight attached to the machine, then stepping on the clutch to release the weight which makes a golf club swing into action. Slow-motion shots of the machine working.
