Originality and components
How to distinguish original configuration, replaced parts, correct replacements and components from different periods.
Originality is not always an on/off switch. An instrument may retain its original body, neck and finish while having replaced potentiometers, speakers, switches or tuners.
Create a list of relevant components and classify them as verified original, consistent but unverified, replaced, modified or uncertain.
This reduces absolute claims and makes it easier to update the assessment when new documentation appears.
For an important item, component-level detail is more useful than one overall “originality percentage”.
A “period-correct” component belongs to a type and period consistent with the item. This can matter in restoration, but it does not mean the component was originally fitted to that example.
Distinguish at least three cases: original to the example, an original replacement from the same period, and a modern compatible replacement.
Functionally, all three may work very well; historically and from a collector perspective, they tell different stories.
When documenting a restoration, state exactly what level of originality you can support.
Not every component has the same historical weight. Some parts are designed to wear out or be replaced during the working life of the item.
Replacing strings, batteries or routine service parts does not carry the same meaning as a complete refinish, structural modification or replacement of a component strongly associated with the model’s identity.
The distinction depends on the category: document what counts as normal maintenance and what changes the historical configuration.
This avoids both penalising necessary work and minimising replacements that may matter to a collector.
If you replace a component for practical use, retain the original parts whenever it is sensible to do so. Label them and document which instrument they came from.
A future buyer may want to restore the previous configuration or simply verify the history of the intervention.
Keeping the parts does not erase the modification, but it reduces information loss and can materially improve real reversibility.
Do not reinstall deteriorated or unsafe parts simply to claim “original”; originality and safety must be treated separately.
