Antique 1870s Keuffel & Esser (K&E) 24 Inch Wooden T-Square Rare First-Generation Early N.Y. Eagle Trademark — Circa 1870-1875
An extraordinary opportunity to own a rare, historically significant piece of 19th-century American industrial history. This antique drafting tool was manufactured in New York City by the renowned brand Keuffel & Esser (K&E) between 1870 and 1875—a brief, highly collectible era representing the company’s earliest days.
Historical Significance & Authenticity
Its absolute authenticity and pre-1875 age are confirmed by three key physical features highly prized by early tool collectors:
- The Early Eagle Trademark: Features the distinct eagle with one claw resting on a ball.
- Crisp Text Stamp: Clear, legible "TRADE MARK" stamp directly beneath the eagle.
- The "N.Y." Designation: This stamp was exclusively used before K&E shifted its manufacturing facilities across the river to Hoboken, New Jersey, in 1875.
This rare combination firmly places this instrument in K&E’s coveted first-generation production period.
