From historian Ron Cummings:
"I knew Miles Gupton.
The car, in the Martin photo, started out as the original Hans Adam Platypus.
Hans modeled the Platypus chassis after the PAM Automotive Merlyn that
they had been racing, with a Corvair motor. I watched Hans build the first
Platypus frame on two saw horses using only a tape measure, hacksaw, and
gas welder. The Merlyn frame was sitting on a pair of saw horses next to
the new frame.
Hans used larger tube
material because of cracking in the old car's frame. This Platypus started
out with Gupton's Porsche Spyder motor. Miles later bought a spare Lotus
19 body from Jack Nethercutt and installed that body on the car. He then
installed one of those little Oldsmobile ( BOP ) aluminum V8 motors. He
later installed a Ford 'Small Block' motor. For some reason Miles kept
changing the name of the car with each upgrade. Miles and Denny Harrison
traded off rides with the last configuration.
I will try to locate some
of the other names for the car. One thing that I used to kid Miles about
was, he advertised the car as a Lotus 19 when he finally attempted to sell
(5-4-11) From Robert Graham:
"When it had the Porsche engine he called it "The Platypus Porsche"
and "Porschemitderasschoppedoff", all one word, which he had lettered across
the back, under the spoiler.
Below is a decal I made for him and the Platypus Porsche he raced
for Hans Adams at PAM Automotive. It's on an old tool box I used at the
time. It shows a helmeted Platypus with a Carrera engine in the back.
