Authenticity
We verify markings, materials, stamp quality and mass differences across editions. When in doubt — we say so. Transparent notes > wishful thinking.
We’re an independent, Netherlands-based project documenting the wind-up yellow “jumping” chicken — its origins, variants, EU price ranges, restoration and authentication. No hype — just working parts.
Years documenting clockwork
Units inspected & restored
Collectors advised
Focus on European markets
We focus on a single icon — the Meadow Hopper™ — to deliver depth that broad toy blogs can’t. We document mechanisms, production eras and materials; we publish practical care methods for the Dutch climate; and we train collectors to identify originals without damaging value.
Principles that shape every guide and consultation.
We verify markings, materials, stamp quality and mass differences across editions. When in doubt — we say so. Transparent notes > wishful thinking.
We turn workshop notes into clear, step-by-step guides you can use at home — no special tools required.
Care methods that stabilize, not over-restore. Original parts stay where possible to protect long-term value.
A friendly EU-centric space where newcomers and experts trade tips, references and repair contacts.
Specialist services around one model, done really well.
Construction seams, tinplate thickness, cam geometry and winding key types — all compared against our reference units to confirm period-correct builds.
We break down the jump engine, common failure points, safe lubricants and the effect of body mass on amplitude — with photos and exploded diagrams.
EU price bands by condition, shipping advice and storage best practices for NL humidity.
