Unlikely to be seen again, four of the earliest and very rarest of the Oliver car motors. Top left is the Jaguar. Top right the Battleaxe. Bottom left is a Fury based motor, although little has ever been published about this. These and the Nine Port, present but lurking in a car, are all based on aero engines. Bottom right is the first production motor specifically designed for a car, the RV, later named the Tiger Mk I. A second version of this with ball raced cranks was the RVB. Missing from the photo is the first motor Olivers built from scratch as a twinshaft, the disc valve prototype from Busy and the DV, disc valve, foot mounted model of which only one is known to exist. We do have photos of these variants as well as the more common RVB MKII available in our Oliver article Diesel domination.

Thanks to the owner for permission to publish a photo of these motors.
