Following on from David Herbert's post, 9th photo down on this site:

Looks the same as your second photo. Two dash panels the same suggests this was an authorised mod. Could this be an interim modification to use up earlier dash panels when the later instruments started coming into use? Or a later field mod to replace damaged instruments from an earlier (civvy style) dash?
Then again, could a shipment of the civvy instruments have been lost on it's way to Australia? i.e. plenty of dash panels, but no instruments?
