Thanks Andy.
Nah, Norfolk is mainly flat !
Most pics show chocks only at the front ( if used at all ), and were probably a precaution for engine start and ground running anyway.
Apart from that, it would have been extremely tricky trying to place a second set on the display base. I had enough problems getting the boarding ladder attached - lost the ladder when it dropped off and vanished into the abyss, so had to "steal" one from another Mossie kit, and that took bl**dy ages to fit. Look closely, and you'll notice it doesn't touch the "ground" as it's supposed to, as I just couldn't get good enough access.
