Schrade Safety Push Button Folding Hunter (Switchblade Pocket Knife), Antique

Antique Schrade Safety Push Button Folding Hunter (Switchblade Pocket Knife), circa 1920s-1930s. I believe this model is designated 15433/4.
Overall length closed is ~4-7/8", open is ~8-3/16"; clip-point blade length is ~3-5/8" from tang to tip, ~3-1/16" from tang to tip (obviously has been shortened a bit over time). Stained picked-bone grips with no obvious defects. Functional, push-button, spring, and lock all operate very well; lockup when open is a bit loose. Blade is stamped on ricasso, "SCHRADE / CUT CO / WALDEN NY" and on opposit, "U.S. PATS. / FEB.13,06 / FEB.26,07".
About fair to good condition overall. Sold as is; no warranty implied or given.
