Thanks Cornish Jack, didnt know any were there that late on. Dont suppose you have any photos of it, as i've only seen one standing under the frame of a hangar.
As for getting into the cockpit it was fairly straight forward with a footstep on either undecarriage leg, and foot holds in the port fuselage side.
But one Boscombe test pilot was noted as saying "Access to the cockpit is difficult; it is recommended that it be made impossible!"
