Value & Age

Estimated Market ValueNot an official valuation

Approximately US$8–20 per board foot for ordinary kiln-dried lumber; premium figured or wide boards cost more.

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

Wood Age Estimate
The piece appears workshop-used or reclaimed, but visible wear and oxidation do not reliably establish tree age; likely decades old as an object.

Common Uses

Furniture, cabinetry, flooring, gunstocks, veneer, interior trim, carving, and turned objects.

Geographic Origin

Native mainly to eastern and central North America, especially the Midwest and Appalachians.

Workability

Generally machines, sands, glues, and finishes well, though tearout can occur near irregular grain and dark dust may mark adjacent surfaces.

Finish Recommendations

Apply a sanding sealer, then oil, shellac, lacquer, or satin polyurethane; wipe-on oil enhances depth, while careful surface preparation prevents uneven sheen.

Notable Features

Distinctive walnut color, moderate weight, good dimensional stability, and attractive understated grain; the curved component may be an older handle or fitting.
