Off topic digression:
It should be noted that a NOS part is not necessarily pristine, even if it comes in a box. The part might have been stored poorly and/or thrown around over the past 50 or so years. If you are buying a NOS part, you should ask for photos of the box and of the part - these things affect the cost/value of the item. Paint, chrome, overall-finish/appearance, and rubber components might be in bad (non new) condition.
