The Kombi will be part of Shannons Melbourne summer auction on December 8.
With values of "Split Window" Kombis soaring, Shannons national auction manager Christophe Boribon said it was becoming increasingly rare to find worthwhile unmolested examples for restoration.

"This wonderful time-warp example presents a rare opportunity for the Kombi enthusiast," Boribon said.
"It has created enormous interest so far and we expect some feverish bidding from floor, telephone and also online bidders."
Shannons expects the Kombi to sell with no reserve in the A$8000-A$12,000 ($8660-$13,000) range, but Boribon admitted this might be a conservative estimate.
"A multiple award-winning 1966 VW Campervan sold to an online buyer for A$74,000 at our September auction in Melbourne, so it will really depend on how much enthusiasts want it," he said.
