No, I don't think so. They would have no specialist skill or knowledge about this stuff. They might just as easily be handling breadmaking equipment for a baker gone bust or shoes or bicycles.
Don't be _too_ sure. There's money involved.
I encountered this kind of 'auction insider subterfuge' once. It was during the auction of equipment at Sydney's old Cockatoo Island naval dockyards. I went to the inspection out of curiosity, but found one series of items that sent me into 'must have' hysterics. They had about eight 'steam oscilloscopes'. Yep! Mechanical oscilloscopes, for diagnosing steam engines. Beautiful wood instrument cases, containing an instrument that consisted of a kind of steampunk overkill contraption. Basically a graphpaper cylinder, that gets rotated by a cord you attach to some moving part on the steam engine. The graph pen gets moved up and down by steam pressure from where ever you attach the 'probe' (a pipe). So you get a diagram of pressure vs movement. Very cool. I'd never seen or heard of these before, but I have a bit of a steam fetish, so....
Scraped together what cash I could, and went to the all-day auction. Determined to get one.
Those items were late in the day. All day, every single item in the catalog was put up for bidding individually, and the auctioneer tried hard to prompt more bids.
Getting close to the 'steam scopes', the crowd had thinned a lot, I was getting excited.
Then he gets to the first of them. Suddenly "And now, the following 8 items together. What am I bid for them all?" Some guy in an expensive suit makes a way-high bid I can't hope to match. Autioneer: "Thank you sir, any more... no... done! Sold to... Now next item..."
It all happened too fast for me to get over my shock and start yelling. Also I was too shy those days to make a scene anyway. So shit...
He'd obviously been paid to make sure that guy in the suit got them all.
Still makes me angry.
