Some discussion over on another forum I frequent, led me to doing a bit of searching on the above topic, which had also come up in a PM convo CyberJack and I had, some time back.

The ODK connection is that retired Mod 'Grumpy' is a member of the Chamberlain clan, and actually drove this thing once...

Fascinating reading, this! https://primotipo.com/2015/07/24/chamberlain-8-by-john-medley-and-mark-bisset/


Cheers,
Gadge

Hi Gadge and bigted
Many thanks Gadge for re-igniting this subject.

Grumpy is such a complex and talented man.
As a son, he had to walk in the shadow of his famous father.

As an adult, he became an engineer in his own right.
A guarded man, he never bragged about his own achievements,
beyond working for one of the great auto makers.

I wouldn't say he was born with a silver spoon in mouth.
He paid his way.

It's quaint - both Lamborghini's and Chamberlain's fascination
with the tractor and the automobile...

I feel ODK is so lucky for Grumpy contributing, over many years,
to these ODK forums.

Here is a gallery of my research and a bit more ...

Hi Gadge, bigted and Jack

Yes it's interesting engineering ,I've seen a few Patents from about 1920 with opposed piston engines.

When I see the video of the Chamberlain 8 running the phrase Smoke 'Em If You Got 'Em comes to mind.

The opposed piston engine has mainly been used in trains, tanks and marine use.
