AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Not reliably determinable from this photograph; surface wear and oxidation suggest finished, aged material rather than freshly milled stock.

Common Uses

Fine furniture, cabinetry, architectural paneling, flooring, gunstocks, turning, veneer, and musical instruments.

Geographic Origin

Eastern and central North America, especially the Midwest and Appalachian regions.

Workability

Generally machines, sands, glues, and finishes well; interlocked areas can show some tearout. Pre-drilling is advisable for fasteners.

Finish Recommendations

Use a clear oil, wiping varnish, lacquer, or polyurethane after thorough sanding; a seal coat can even absorption and enhance contrast.

Notable Features

Distinctive dark brown color, attractive subdued figure, good dimensional stability, and moderate weight.
