-------Tim is correct on the rarity versus build-date aspect.
-------Something to remember with broach-marks is that the broaching machines used had a time line with respect to wear. In other words, not all original broach-marks look the same. The scratches grow more distinct as the broachers wear out. Dont judge one set of broach-marks against another as they both could be original. Just make sure those lines are straight!...........Bill S
