Insert construction evidence
16-hole chimney — Introduced during 1946; not useful as a precise clue on later inserts. Known period: 1946–9999.

Tapered cam-spring end — Minor cam-spring alteration reported around 1988/89. Known period: 1988–9999. Dating evidence: Supporting comparison (A useful illustrated or photographed comparison.

Solid flint-wheel rivet — Introduced around 1961; overlaps hollow rivets for several years. Known period: 1961–9999.

Additional reverse-side text — Additional reverse text appears around 1975/76. Known period: 1975–9999.

Regular insert date code use — Date codes are reported as fully in use by 1984. Known period: 1984–9999. Dating evidence: Primary dating clue (An established factory date code or a directly relevant stamp system. Check the complete marking and model type; it is not a certificate of authenticity.).

Interpretation: References may cover multiple years. A documented insert date is not proof of its case production date, and special Replica stamps require separate interpretation.
