Their 1946 Beetle is the famous Therese Hanael Beetle, the first privately-owned Volkswagen to ever come to Australia. She had bought it from a British Officer of the Occupational Forces in Germany, and shipped it with her when she emigrated to Australia with her son in 1951. She was joining her husband Ted, who had been interned in Australia during the war. The Hanaels used the car for daily transportation for the next 10 years. In 1961 it was the result of a 4-month search by Volkswagen Australasia Ltd, when they were looking for the oldest VW in Australia to celebrate the 100,000th Australian VW.
In a ceremony at the Clayton factory, the then premier of Victoria, Henry Bolte, presented Mr and Mrs Hanael with the brand new 100,000th VW - in exchange for their '46. VW used the black '46 in advertising and promotion for a while, then the car was placed in the admin foyer at Clayton for a number of years. Later it was shipped to Sydney when LNC Industries took over the VW franchise. It went on a few display tours and sat in the North Ryde head office for a while as well as the showroom at Lanock Motors St Leonards (where I remember seeing it in the late '70s). At one stage it was damaged, so LNC took the opportunity to 'renovate' it and they resprayed it from black to a light grey/blue.
It was moved to Green's Motorcade Museum at Leppington in the early '80s when LNC sold it, where it sat alongside one of the last Clayton '76 Beetles. When that museum closed it went up to Gilltrap's Museum on the Gold Coast and it sat beside one of the Chitty Chitty Bang Bang film cars and Genevieve (from the 1950s British film). It was sold to Peter Briggs in the mid-'80s and moved to his mueum in York, where I saw it again in 1987. For a while he had a 'branch' museum at Fremantle and the '46 was moved there, but it closed a few years ago and the '46 has been back at York since.
It's probably the most historic VW in Australia. I believe a few VW enthusiasts have tried to buy it from Peter Briggs, but he is aware of its history and won't sell.
