Stamped steel rails, cast-aluminum bases, and acid‑etched glass each age differently, offering cross‑checks that strengthen attribution. Crisp stamp edges soften predictably with long use; cast marks keep rounded fillets; etched marks reveal micro pitting. Compare surfaces near contact points: oxidation rings under screws, scuff halos, and consistent grime gradients help verify genuine working life instead of contrived distress.
