I'm guessing "unknown government body" is short hand for "I'm not dobbing in my contact who gives us all this stuff to sell" ?
I work for a company who owns an auction business (cars) - it is super locked down in terms of the auction house having a legal responsibility to know who is selling things and that they are who they say they are to stop money laundering. In my experience, based on the automotive sector, it is utterly unfeasible that the auction house wouldn't know the "government body" involved and also the name of thee disposal agent who would have authorised sale and the courier who delivered the items.
anyway, I'm getting annoyed, and just edited out anything liablous or that would get me in trouble with the mods - how you've kept calm I don't know!
