Press Button Knife Co medium double Tortoise celluloid automatic knife

Antique Press Button Knife Co medium double with tortoise celluloid handles made in Walden, NY sometime between 1892 and 1923. It was designated the model #102 and measures 3 3/8" closed and 6 7/16 inches with both blades open with brass liners and nickel silver buttons. It is the middle one of three sizes of switchblade doubles made by the company. The blades are both sharpened and short, but still decent with some peppering and scratches. Both blades are marked PRESS BUTTON KNIFE CO WALDEN NY and both have patent number 470605 on the back. The tortoise celluloid scales are in very good condition with no cracks. The knife works well with both blade tips below the liners closed, good snap and good lockup. Small blade has some kickback, but usually ends up locked if you hold the button longer when opening. G+ condition.
