Possible this is Made in early 1900's for WW1? I found this article online just now:
"In 1843, Frederick Stanley founded a small shop in New Britain to manufacture bolts, hinges, and other hardware products for sale to local residents. Years of quality products and innovation followed and Stanley’s enterprise grew into one of the largest and most successful hardware companies in the world. Throughout Stanley’s success, the company remained dedicated to not only promoting its brand and expanding its product lines but also to improving the lives of those in the New Britain community.

"Frederick Stanley and William Hart Forge Success in Hardware Business
The company known to New Britain residents for over a century as Stanley Works actually got its start as two separate companies. Frederick Stanley’s enterprise took many forms involving a variety of business partners before he established his wrought-iron bolt manufactory in 1843. His success in the bolt business soon encouraged Stanley to expand into forging other types of hardware such as hooks and hinges. This hardware business became Stanley Works in 1852.

Two years later, in 1854, Stanley hired 19-year-old William Hart, who turned out to be such a visionary that he received a promotion to secretary/treasurer of the company after just a few months. Hart proved the driving force behind much of the company’s success, designing new machinery and inventing the process for cold rolling steel.
While Hart engineered the rise of Stanley Works, Frederick Stanley began establishing a company tradition of community service—one that continues to this day. Stanley involved himself in the creation of a local gas light company in 1855 and, two years later, proved instrumental in helping bring the first running water to New Britain. In 1871, he even served as New Britain’s first mayor.

By the turn of the century, the name Stanley was a fixture, not only in New Britain but at hardware stores across the country. By the time of William Hart’s passing in 1919, the company’s sales had grown from a mere $7,000 a year to $11.3 million over the prior six decades and left Stanley poised for the next stage of its development.
