Flaws to Note
Significant surface rust and pitting; wood handle shows darkening from age and oil; mechanical movement may be restricted by corrosion (needs cleaning/oiling).
Selling Guide
Where to Sell
eBay is the primary market for vintage tools. Etsy is excellent if marketed as 'industrial decor'. Local antique malls in rural areas are also viable.
Selling Tips
Do not aggressively sand or wire-brush the metal as it destroys the antique patina; use a light coat of 3-in-1 oil to stop further rust. Use keywords: 'Trimo', 'Monkey Wrench', 'Antique Tool', 'Trimont Mfg Co', '6 inch'. Shipping is easy via USPS Ground Advantage due to its small size and heavy weight.
