Is anyone familiar with this pendulum? It would seem that there is something missing as, while hanging the bob does not hang straight.

I just looked at mine Greg.It's the real deal and what it has is a tab coming down off the back of the pendulum which sits in front of a bend in the back of that clip the rating nut is underneath off.That tab off the pendulum along with that bend in the back of that clip keeps the rating assembly straight.I do not see the inside bend or the pendulum tab on yours.

Would you be able to suppy a photo? I would like to correct this problem. thanks
