Selling into this sector
What to expect
Equipment from this sector usually arrives with a mix of documentation: some items tagged and recorded, some with nothing at all. Send what exists. A partial record is worth more than a claim that records exist.
Mixed lots are normal. We do not ask you to separate the documented items from the rest before sending a list.

Yes. The body is the value in this category.
Are large knife gates of interest?
Yes, particularly stainless and duplex bodies.
