In my opinion that is evidence of a horrible sharpening job. By the early 60s buck was stamping blanks out of steel, and wasn't using file blades anymore.
It looks like very deep gouges from a bench grinder that was used in a dim witted attempt to sharpen it. Then it was buffed to try to hide them. It didn't work.
