Richard Scaldwell's 1908/1919 GN JAP. JAP were well known for their V-twin bike engines but they also built engines for some of the earliest planes and dirigibles. Apparently there's a sister engine to the one in this car in the science museum. The wooden chassis is a 1919 Grand Prix GN design and houses the familiar GN chain-gang transmission beneath the seats. It's the way that Richard has brought all these elements together that deserves most appreciation.
