It was a Matchless MX side valve engine, which at some point in its life had the water cooled heads and barrels replaced by those from a Matchless X motorcycle engine.
I have built a MX4 OHV engine for it. Pic below.
Also have some bits to rebuild the original engine to water cooled spec at some point.



My wife and I just finished watching the movie The Party with Peter Sellers. The M3W in the movie had what looks like the Matchless engine in your photo. The car had 2 small doors also.

I would like to know more about that car. Year? Model? Water or air cooled? Can anyone help?
