Era / Decade
1920s-1940s
Material
Drop-forged carbon steel with a cast iron adjustment nut.
Condition
Good. Shows surface oxidation (rust), typical pitting for its age, and minor 'mushrooming' on the jaw edges from hammering, but the adjustment mechanism appears functional.
Demand Level
Moderate. High demand among tool restorers and vintage car enthusiasts, but high supply makes it a slower mover unless priced competitively.

$12.00 - $35.00
Estimated Retail Value
$15.00 - $25.00 (Modern equivalent)
Comparable Sales
Recent eBay sold listings for 'Vintage Auto Wrench Made in USA' range from $10 for rusty examples to $30+ for those with clear 'Ford' script or in cleaned, working condition.
Description
This is a classic vintage 'Auto' style adjustable wrench, often referred to as a Ford monkey wrench because they were frequently included in the original Model T and Model A tool kits. It features a 90-degree jaw and a knurled adjustment nut. It is marked 'MADE IN U.S.A.' and 'AUTO' on the handle, indicating a mass-produced but high-quality domestic tool from the early-to-mid 20th century.
Key Features
American-made tool history; compatible with vintage Ford collector markets; heavy-duty drop-forged construction; iconic 'Monkey Wrench' silhouette.
Authenticity Indicators
High confidence. The 'MADE IN U.S.A.' and 'AUTO' stampings are consistent with legitimate period-correct automotive tools provided by OEMs in the pre-war era.
Flaws to Note
Significant surface rust and patina; minor steel deformation on the head; no specific manufacturer logo (e.g., Ford script or VLW) which limits top-tier collector value.
Selling Guide
Where to Sell
eBay (best for broad tool collectors), Etsy (if marketed as 'industrial decor'), or local Antique Malls/Swap Meets for car enthusiasts.
Selling Tips
Do not over-clean; many tool collectors prefer the original patina. Use a light coat of 3-in-1 oil to prevent further rust. Include keywords like 'Model T', 'Model A', 'Rat Rod', and 'Ford Tool Kit' in your listing title.
