Schrade Cut Co medium double Hall Topeka Ivory Cell Spey/spear combo Office knife

This knife was made by the Schrade Cutlery Co of Walden, NY sometime between 1916 and 1946. This knife was designated the O7404W office knife with Ivory celluloid scales and brass liners. It has two blades that are each activated by pressing one of two buttons (one on each side). The knife measures 3 3/8" closed and 7 1/4" with both blades open. The knife has seen light use over the years but both blades are nearly full and have much of the original finish still visible. The spear blade is stamped SCHRADE CUT CO WALDEN NY and has some spotting on both sides. The Spey blade is marked with three patent dates, 09,10 & 16 and is extra nice. The knife works well with both blades seated well closed, both open fully when buttons are pressed and both lock open nicely. EX- condition. Most of these actually said OFFICE KNIFE on the handle, but this is an office style knife with advertising instead.
