That's Colin Ngan in the white with green stripe Cooper in the earlier photo. Apparently the Lawrences created one good car and one not-so good out of the parts of the 2 Bobtails. The other one, with Doug L at the wheel(almost) is at the front end of the line-up, third fastest in the green with white stripe car. Doug looks a bit more portly and middle-aged than Ngan in this photo.
Don't think I'm getting too far off-topic here, there are three Buckler-type cars in the middle of the line-up - the Elva-Ford, Marshall's Buckler, and the Orchid, which I think had an AMW body at some stage.

PS John Scurrah's Lotus(clone)-Consul is just off the end of the picture.
