Barron (92) has had such a long career that when asked when he started bowling, he struggled to remember.
"I've been playing bowls for years," he said.
"I can't remember, but I must have been bowling for 50 years. I don't keep records."
His wife of 65 years, Mollie (87), says the dates will be written on the certificates.
She disappears down the hallway and returns a minute later with a huge album full of Barron's achievements, which she places on the dinning room table.
There are 41 South Otago centre titles in total.
"I'd been bowling for a while before I won my first title," he said.
"I was playing cricket before that. I was getting to the end of my cricket days, and someone asked me to play."
The first certificate says "Champion of Champions, 1959".
Barron said he gave up playing in big tournaments about eight years ago, and the last certificate, another champion of champions title, is dated 2000-2001.
Tucked into the middle of the stack is a brightly coloured piece of paper from 1977 - New Zealand Champion.
"He still plays with the old-style bowls," Mollie said.
Barron won the Balclutha championship last week, and will compete in Kaitangata on Saturday for another centre title.
"I haven't been playing much this year," he said.
"I've been playing club bowls on Saturdays."
When asked about a special diet and exercise regime, the Barrons laughed.
"I've got a good wife who looks after me," Barron said.
"We never worry about diets," Mollie said.
"He's got a great garden and he has loads of veges. And he's fit."
Barron still helps at club working bees, and still cuts the grass at the bowling green.
"It keeps you a bit fit, doing something," he said.
