Move into the casting-reference section when the real job is identifying tooling, year clues, or packaging signals.

Use the value-and-history pages when you are trying to understand scarcity, price context, or collector demand.

Jump to the brand hub when you need a tighter manufacturer view.

Use scale hubs when display fit or category size matters more than brand.

Use search when the archive is close but you still need a specific casting, series, or model-year match.
