State year and origin only when verifiable

Year, series and country of manufacture can affect interest and value, especially for certain models.

Use this information only when supported by reliable evidence: serial number, documentation, known production characteristics or other trustworthy sources.

If you only know a range, state it as a range.

Avoid claims such as “1980s vintage” or “made in USA” based only on visual impression.

Accuracy is more valuable than a description that merely sounds more attractive.
