It has a glow element that is spot welded in place where it should be. it looks from this photo that there is only half of an idle bar that is spot welded in place also. I would say it's a factory reject or mistake of some kind that got past QC efforts. If it glows under power, it should work, but I would worry about vibration getting to the incomplete bar and breaking it off. I would save it as an oddity. Post a side view picture of it so we can tell more, please.
Type at you later,
