Our read
The individual advertisement is accessible, but item 4385 is absent from the seller's current vacuum-furnace inventory index. Availability is unresolved. The source photograph shows the vessel, control cabinet and loading hardware, but does not establish current operation or internal condition. Allow for the excluded vacuum equipment and recorder when considering a complete project.
Availability, ownership, operating condition, included components, removal terms and published specifications remain subject to direct confirmation.
