I have a Winchester folding lockblade with wood handle. On the blade it says Winchester with the registered trademark insignia, on the tang it has "440 stainless" and "handmade", the metal band on the top of the handle has the horse and rider etched on both sides, and on the lock mechanism it has the number 29989. Does anybody know anything about this knife or know where I can find out? Any help would be greatly appreciated.
