Lisa Sorrell · Identification

Construction / ID tells

One-maker Guthrie bench. Her site requires an in-person measure.
Pictorial inlay and overlay. Customer drawings appear in Craft in America coverage. Those pictures are not a model number.
No factory SKU line. Period price and wait figures move. Caption the dated source rather than treating a website number as a current list.

Maker-specific markings guidance has not been documented yet. Preserve the complete stamp and compare it against dated sources.
