After the sudden demise of one of the founders, Mario Zammit, and various problems with premises, the Malta Historic Vehicle Trust was wound up, and vehicles, as far as I know with regards to these two Pigs, were sold, and have now been restored by the person who purchased them at the time. I have no contact with the current owner, but will attempt to see if pictures can be obtained. A third, was restored by the Malta police, and is in their collection. The fourth was retained for some time by the military, but has not been seen since, and the barracks where it was were demolished in approximately 2013, and no one I spoke to knows where it ended up.
By the way, whilst attempting to look for some pics of the Malta Pigs, facebook turned up a picture of another Pig, apparently being shipped to Malta in 2016. No idea which one it is, and have never seen it on the island. Pic taken off FB below when said Pig was being onloaded at the shipper’s Essex base. It looks like the Armourgeddon one.
