OK, Derek Bell is driving the Tom Wheatcroft (of Donington Park) entered Brabham Cosworth, while #33 is Derrick Williams. Mike has captioned the RX3 as being Don Grindley. Can anyone help here? I thought with all the signwriting it might have been Rex Findlay. The final photo I don't think even David McKinney can help with!
