They appear to be Quorn accessories divided from the parent unit. Disgraceful.
I think there must be different cultures in different parts of the country. I go to a LOT of farm auctions. That's how I buy most of my equipment. I've never seen or even suspected anything of being sabotaged.
But auctioneers are another matter. I once bought a planter at a farm estate auction for 20k only to discover later that the metering plates and the electronic monitor - which were all sitting on the planter without lot numbers - were being auctioned separately. Fortunately, they were pretty useless without the planter so I got them at a good price. But I sure was pissed off about it. Later that same day, the local Deere dealer found out that I had bought the planter and offered me 45k for it - so I got pretty happy pretty quick even though I didn't sell it. It's been a really good planter for me and was well worth the price I paid.
What makes this story even more interesting is that I had already put a deposit on another older planter at a planter repair specialty shop. The salesman I had worked with was in the crowd that day and DID NOT bid against me. In fact, he even gave me a credit for parts and supplies in exchange for my deposit. Yes, there are honourable people out there.
