Cost band one: establish manufacturer, model, build and document identity
Request clear nameplate and configuration photographs, serial or project references, model text, seller ownership evidence and included manuals or drawings. For older equipment, record changed controls, drives, feeders, lubrication or take-down. A retrofit may be useful, but it creates a new support boundary that must be documented rather than hidden behind the original model name.
Price independent inspection, translation, missing records, electrical-drawing reconciliation, program backup and part-number research as open costs. Hold when the plate, physical build, invoice description or seller authority do not agree. A low offer can become expensive before the buyer knows which cylinder, control backup or replacement part should be ordered.
