In 1968 and 1969, Bob Britton built a series of cars based on the design of the Brabham BT23. The first were for the Rorstan and Mildren teams, and were named after their new owners, but later cars were raced as Rennmax BN3s.

In 1968, Denny Hulme entered the ex-Winkelmann/Rindt F2 Brabham BT23 [5] in the 1968 Tasman series. At the very first race, Pukekohe's NZ GP, he crashed the car heavily and the wreck was acquired by Feo Stanton and Ian Rorison of Rorstan Racing. They sent it to Bob Britton but, instead of repairing it, Britton built a jig and sent a new frame back to Rorstan. This car was built up with a 2.5-litre Climax V8 as the Rorstan Mk 1. The old wrecked BT23 frame went on the roof of Britton's workshop, but that's another story.

After the Rorstan and a car built for Alec Mildren's team which was always known as the Mildren, it would appear that five more cars were built with the name Rennmax, mostly in 1969 but with one straggler appearing at the start of 1971. A further car was later completed using a spare frame that had been built for Mildren. The Rorstan was later wrecked, but the Mildren and all the other six are known to still exist.

The remains of the car were later sold to Alan Hamilton for the Porsche engine, and the rest of the car was sold to Denis Lupton, who wanted the remaining Brabham BT23 components. What was left passed to Syd Fisher, who started to restore the car to the original Rorstan-Climax specification, but his workshop was destroyed by a fire started by a neighbour's incinerator, and all that was left of the Rorstan was destroyed..

'the Rennmax Palliser'

Bob Britton built up a spare frame for Alec Mildren in 1968. It remained unused, and was acquired by Don Baker who fitted it with some Palliser suspension components. The car was finished but still did not have an engine fitted when it was sold to Bob Johns in 1971. Johns also did not use it, and sold it to his brother Rod Johns in 1972. Then sold to David Booth and fitted with a 1300cc Toyota Corolla engine for Australian F3 in 1974. Sold to Mal Brewster 1975, then to Craig Gibbs 1976, to Keith McDermott 1982, and then to John Allison in 1984. Allison crashed the car at Amaroo Park and died as a result of his injuries. The car then was purchased by Laurie Knight (Wagga, Australia) in 1990, and he and Gary Neilsen (Victoria) rebuilt the car to its original Palliser specifications. Sold to Chad Wheeler (Ipswich, Queensland) 2000, and raced in Australian historics from 2003 to 2006. Advertised on various occasions over the next ten years, and sold early 2017 to Ian Gray (Brisbane).

Ian Gray (Australia) 2017

Lloyd Cleaver also owns a car that appears to have a Rennmax chassis, but its full history is not yet known. Bryan Miller adds that Ian Cook (the one that lived in NSW, not the one from Victoria who died) and Bob Vickers built up a car on a spare Mildren-Rennmax chassis, fitted a 1300cc Fiat 128 engine for Australian Formula 3, and called it the Squire CV3.

Thanks to Ray Bell, Bryan Miller, Gary Neilsen, Matt Ruggles, Vaughan Stibbard and others for their help constructing these histories. All and any help would be gratefully received. Please contact Allen Brown (allen@oldracingcars.com) if you can add anything to our understanding of these cars.
