It died in that very race...

At the end of the first lap the crank broke, bits escaping took out the gear linkage and Frank couldn't knock it out of gear so all the bits were still whirring around out of control and it all began at pretty much the fastest point on the circuit.

After Frank Matich's crash in the Lotus 19B in July (also at Lakeside) the Mildren Maserati was expected to walk away with the ATT, but it fell into Pete Geoghegan's lap for the second time.

Sold less the damaged Maserati engine to Ross Ambrose in Tasmania, he fitted a Climax (about a 2.2-litre as I recall) and raced it with success on the Apple Isle. Later it had an Olds or Buick engine fitted, I think an Oldsmobile, and it continued racing for some years. It's still out there somewhere.

For the greater part of its life it was known as a Rennmax, though the Wikipedia article on it states it was copied from a Lotus 19 chassis while in fact it was basically a Lotus 23 with a bigger engine bay, bigger brakes and a restyled body. It was, of course, a Bob Britton build and he had Mildren's 23 chassis on hand to copy.
