You may be asking the following questions:
- Why is the vendor selling?
- What was the asset doing previously?
- Is it a regular vendor?
- Engine/maintenance/repair history of the asset?
On the sale listing of industrial assets, there should be a section called 'Service History' and there you will find the logbook.
However, if the logbook does not appear on the website, it should be assumed that the asset does not have a logbook or service history.
