Sorry but no, you need to remove a rear wheel to get a good picture of how it works, but basically the Martian rear end is similar to the Watford version but heavier duty and with a conventional spiral bevel diff instead of a worm and wheel. Each wheel has a large drum with a vertical air actuator, all four actuators running from a common feed. It could have been even better if the actuators had a spring for parking, but the simple solution of spring secondary/park brakes was not thought of until the 60s and parking was catered for by a large disc on the transfer.
