Elfin chassis number 5 of the first batch of six Streamliners built by Garry Cooper's fledgling Elfin Sports Cars.
Completed in May 1960 as the first fully factory assembled Elfin - most cars were delivered as rolling chassis.
Built for Russ Court of Victoria using a supercharged BMC A series engine and gearbox.
A succession of eleven owners have ensued over the past sixty four years and it has not missed a year of competition - 250 plus race meetings at best guess.
