Discovery cards — GM keeps these until revealed

Three sealed bundle labels

Bundle A: 4 Bell Row, square workshop stamp. Bundle B: 8 Bell Row, square workshop stamp. Bundle C: Mill Cottage, leaf stamp. All three postmarks fall in Ada’s final route week. Write a current destination beside each old one. Try this: Make three forwarding hypotheses without opening the bundles.

Street-change register

Bell Row renamed Cedar Walk. Old even numbers increased by eight; workshop stamp remains square. Mill Cottage: unchanged name and leaf stamp; public entrance moved to Orchard Lane. Apply changes only to the matching street. Try this: Translate the docket’s addresses and explain which rule does not apply to the cottage.

Ada’s punched route strip

Square route: old Bell 4 → new Cedar 12; old Bell 8 → new Cedar 16. Leaf route: cottage name unchanged; access arrow now points from Orchard Lane. Punched dates match the three bundles’ final-week postmarks. Try this: Cross-check the labels or replace a lost street-change record.

Turntable and custody card

Train held on red. Ren secures lock; select POST; Ren confirms the ramp. Alternative: carry the sealed drum through the passenger passage. Handover receipt blanks: receiving clerk, volunteer, start time, three bundle seals intact. Try this: Choose rerouting or carrying, then fill the custody receipt if delivery is deferred.
