Yes, definitely a Bonney, called "The Masterpiece," patented in 1902-3 I believe, and pretty sought after. Bonney sold so many of those they had an unidentified plant in NY making them exclusively under contract. Possibly the largest single impetus for moving to Allentown, building a bigger plant and transitioning into the mechanics tool market in 1909. I've been searching for one of those in the wild for a couple years............still no luck. Very nice find!!
