CASE TESTED XX 6161L Bone switchblade knife

Very nice example of a vintage CASE TESTED XX 6161L bone handled lever activated switchblade. This knife was made sometime between 1920 and 1940 by the WR CASE & Sons Co of Bradford PA and it has nickel silver liners, bolsters and lever and jigged bone scales (handles). The blade is 98% full, or better with nearly all of the original factory finish intact! It's stamped CASE TESTED XX on the tang and CASE'S TESTED XX stamped into the front bottom bolster. The blade has one little "pock mark" near the top of the slope which I believe is a factory defect, but hardly noticeable on this gorgeous old switchblade. The knife works great with blade tip seating good in the well closed, strong snap and tight lockup! The bone scales are in great condition with no cracks or chips. One of the nicest examples I've ever seen.
