I've taken a couple more pictures and as far as I can see with the exception of the driveshafts it looks standard cougar 2000 at the back to me. The rear wishbones are held on with pins and circlips that go through what looks like a plastic mount that is then screwed/bolted onto the chassis.



I see what you mean about the front gate missing, although the servo doesn't look any bigger than a normal servo, it is an Acoms AS-12 servo.
