Perhaps this accounts for the fact that, on the Police side, only Hare was wounded during the whole shootout. Certainly the Armour saved the user from direct hits to areas which it covered. For those areas not covered, naturally one was vulnerable. It was this lack of total armour that brought down Ned, thanks to Sgt Steele, and accounted for Joe. Working out who owned which suit of armour is not easy.
Various sources claim the same sets for different gang members.
We know where the four sets are located, but as to which set, or indeed which piece belonged to which set and in turn to which person, is at times confusing. This back-plate belonged to Steve Hart's set, and could clearly be seen in the photo taken of the ashes of the Inn. After the Inn was fired, and collapsed, two sets of armour were found and photographed. They were Dan Kelly's and Steve Hart's. There were two sets taken intact, and to which we can be sure of ownership.
