E. WECK & Son 3 3/8" Medium Double Pearl vintage automatic knife made by Schrade

Vintage E. WECK & SON 3 3/8" Medium Double Mother of Pearl automatic knife made by Schrade Cut Co of Walden, NY sometime between 1916 and 1940. The knife measures 3 3/8" closed and 7 1/8 inches open with nickel silver liners, buttons, safeties & pins. It's a Spear/pen blade combo with both blades being 98% full, or better and shiny with light scratches and some spotting with main blade stamped SCHRADE CUT CO WALDEN NY and the pen blade US PATS DEC 21, 09, SEPT 13, 10 and JUNE 6, 16. The genuine Mother of Pearl scales are beautiful and original, but the front scale has some cracks around the button and safety. Back scale is great. The knife works well with both blade tips below the liners closed, open fully and excellent lockup with just a hint of movement on each tip open. Doesn't rattle if shaken with blades open. (slight kickback on both blades) Both safeties work. VG+ condition.
