Stolen Awards.

[Art]

Some of those items seemed to be valuable in that they were so unique, i.e. the St. George presentation bugle, St. George presentation plate, Imperial Silver Goblet, Imperial Helmets. Surely these held a higher cash potential than the metals they were constructed of. These wouldn't be something you could sell on a table at a market to foreigners. If they weren't specifically targetting these items, it seems as if it would be pointless to steal them, unless they were hoping to sell them for the metal content. Not a very smart way to steal. They were either very well organized crooks ( hired to steal for collector, or forsale overseas ) or very stupid ( smash and grab and sell to pawn shop )

My guess ---> rich collector.
