First it was the JUMOs in the 1930's and 40's, then some decades ago, ZOCHE crossed the stage, now this one is looking interesting. - ! Those Germans are certainly... persistent.

But a turbine - whatever it's price - would be easier to strip/assemble than these nightmares.

Don't forget the Guiberson 9 cylinder radial diesel aircraft engine.

Nev. Morris of Dalby has one in his extensive collection of engines, machinery, vehicles. He showed it at the Hack Day in Toowoomba a few years ago. I have seen it running. Amongst others, Nev has a Mk.20 Merlin that runs. a Hall-Scott 36 litre V12 installed in a vintage Chev. truck and a GMC V12 11.1 litre truck engine he has made into a replica of a veteran raceabout. All are goers.

Cadillac built a radial diesel around 1930, but it did not go anywhere.

Nev. also has an ex-RAAF Caribou radial engine that runs after a little attention. Then there is the remarkable replica veteran car that has a 16 litre four cylinder engine that Nev made.154915
