The wooden replica flying machines are not toys.
A scroll inserted in a "secret compartment" slotted behind the plane's propeller and each helicopter's red nose contains an individual number. "They are a collector's item, limited edition," Mr Ball said.
The pair have spent many hours each week working on the project.
Each souvenir has "Wairarapa 2015" laser-cut on the wings or rotor blades, with each hand-made piece using recycled mahogany handrails from a staircase and donated totara and other wood.
Mr Ball, a long-time "sheddie," said it had been hard work.
"I've had many sleepless nights and got RSI at times," he said. Mr Carter, who has been a member of Henley Men's Shed for only nine weeks or so, said the shed was a great place to be with other like-minded people.
"I've thoroughly enjoyed being part of this project."
