Schrade Walden pattern 153 Hunters Pride Folding guard switchblade knife etch

Vintage Schrade Walden Hunters Pride Folding guard switchblade knife made in Walden, NY between 1946 and 1956 and designated pattern 153. Measures 4 7/8 inches closed and 8 5/8" open with steel liners, bolsters and guards and nickel silver button and safety. The blade is nearly full with much of the original finish intact and some light scratches and tiny pit spots and I can barely make out the "H" in HUNTERS and PRIDE of the original blade etch, but it does take some effort and angles to the light to see the letters. Blade is stamped SCHRADE WALDEN NY USA on the tang. Black jigged (stagged) synthetic scales are in excellent condition! The knife works well with the blade tip even with the liners closed, good snap and good lockup with just a little movement each way when locked open.  Does rattle if shaken when open as most of these used nearly 100 year old large switchblades do. EX- condition.
