An early test piece made before production to check design, fit and feel.
What it is
A prototype is made to test an idea before a full run. In Chinese manufacturing it is often called 手板. Prototypes may differ from the final product in materials, tolerances and finish.
Why it matters
Prototype photos show the direction, not the final result. Collectors sometimes seek prototypes as one-off pieces.
Also known as: Proto, Sample, 手板, 原型, 样品.
是什么
原型是在正式生产前用来验证想法的试制件，中国制造业常称“手板”。它在材质、公差和表面上可能与最终产品不同。
为什么重要
原型照片展示的是方向，不是最终效果。收藏者有时会把原型当作孤品收藏。
又称：Proto、Sample、手板、原型、样品。
