Baldwin dating guide.
Founded 1890, Gibson from 2001, US production ended 2008 — organ eras poorly documented.
Baldwin dates to 1890 and was for decades one of the biggest names in American keyboard instruments — pianos and organs. The organ side is genuinely hard: public sources cover the company history (a Wurlitzer subsidiary, then Gibson from 2001, with US production ending in December 2008) but not organ generations. Leslie kit numbers give a practical era marker when the console itself doesn't.
No model-by-model serial tables
Baldwin never published serial charts — and no verifiable community table exists. This page is a working dating guide: era markers, plate location and component date codes. The general dating guide covers the component-code route.
Where the serial number lives
- Plate location for Baldwin organs is not documented in public sources we could verify — check the usual spots: underside of the keydesk and the rear rail.

Frequently asked
Why is there no Baldwin organ serial chart?
Because no public one exists — organ-era records never surfaced online. Use the company anchors (Gibson 2001, US production end 2008) and internal component date codes.
